### What Relationship Does Charles’S Law Describe?

Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

## What relationship does Charles’s law describe Brainly?

Expert-verified answer Charles’ law is stated as the volume occupied by a given mass of an ideal gas is directly proportional to the absolute temperature of the gas at constant pressure conditions. So, according to this law, as the temperature of any gas is increased, the volume of the gas increases.

## Is Charles law a direct or inverse relationship?

Charles’s law states that volume and absolute temperature have a direct relationship. Gay-Lussac’s law states that pressure and absolute temperature have a direct relationship. The combined gas law relates pressure, volume and temperature together.

### What type of relationship exists between variables in Charles’s law?

Link to Learning – This video shows how cooling and heating a gas causes its volume to decrease or increase, respectively. These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general: The volume increases as the temperature increases, and decreases as the temperature decreases. Figure 9.12 The volume and temperature are linearly related for 1 mole of methane gas at a constant pressure of 1 atm. If the temperature is in kelvin, volume and temperature are directly proportional. The line stops at 111 K because methane liquefies at this temperature; when extrapolated, it intersects the graph’s origin, representing a temperature of absolute zero.

• The relationship between the volume and temperature of a given amount of gas at constant pressure is known as Charles’s law in recognition of the French scientist and balloon flight pioneer Jacques Alexandre César Charles.
• Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant,

Mathematically, this can be written as: V α T or V = constant · T or V = k · T or V 1 / T 1 = V 2 / T 2 V α T or V = constant · T or V = k · T or V 1 / T 1 = V 2 / T 2 with k being a proportionality constant that depends on the amount and pressure of the gas.

### Is there a proportional relationship between temperature and volume in Charles Law?

Answer and Explanation: Charle’s law states that the volume of a fixed amount of gas is directly proportional to its absolute temperature at a constant pressure. This means that if the temperature of the gas will increase volume will increase.

### Which law is a direct relationship?

Law of diminishing marginal utility.

### Which law has an inverse relationship?

Boyle’s law states that the pressure and volume have an inversely proportional relationship.

#### Which law shows an inverse relationship?

Boyle’s Law – Robert Boyle (1627-1691), an English chemist, is widely considered to be one of the founders of the modern experimental science of chemistry. He discovered that doubling the pressure of an enclosed sample of gas, while keeping its temperature constant, caused the volume of the gas to be reduced by half.

Boyle’s law states that the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant. An inverse relationship is described in this way. As one variable increases in value, the other variable decreases. Physically, what is happening? The gas molecules are moving and are a certain distance apart from one another.

An increase in pressure pushes the molecules closer together, reducing the volume. If the pressure is decreased, the gases are free to move about in a larger volume. Figure $$\PageIndex$$: Robert Boyle. (CC BY-NC; CK-12) Mathematically, Boyle’s law can be expressed by the equation: \ The $$k$$ is a constant for a given sample of gas and depends only on the mass of the gas and the temperature. The table below shows pressure and volume data for a set amount of gas at a constant temperature.

A graph of the data in the table further illustrates the inverse relationship nature of Boyle’s Law (see figure below). Volume is plotted on the $$x$$-axis, with the corresponding pressure on the $$y$$-axis. Figure $$\PageIndex$$: The pressure of a gas decreases as the volume increases, making Boyle’s law an inverse relationship. (CC BY-NC; CK-12) Boyle’s Law can be used to compare changing conditions for a gas. We use $$P_1$$ and $$V_1$$ to stand for the initial pressure and initial volume of a gas.

### Which law has volume and temperature proportional?

Summary – The volume of a gas is inversely proportional to its pressure and directly proportional to its temperature and the amount of gas. Boyle showed that the volume of a sample of a gas is inversely proportional to its pressure ( Boyle’s law ), Charles and Gay-Lussac demonstrated that the volume of a gas is directly proportional to its temperature (in kelvins) at constant pressure ( Charles’s law ), and Avogadro postulated that the volume of a gas is directly proportional to the number of moles of gas present ( Avogadro’s law ).

## What type of relationship is between temperature and volume?

In simple terms, at constant pressure, the volume of a fixed mass of gas is directly proportional to temperature. It can be stated as: ‘The volume of a fixed mass of a gas decreases on cooling it and increases by increasing the temperature.

#### Is volume directly proportional to gas in Charles Law?

According to Charles’s law, the volume of a gas is directly proportional to the number of molecules at constant temperature and pressure. No worries!

## Why is Charles law a direct relationship?

Charle’s Law – Definition, Formula, Derivation, Application Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. The law also states that the Kelvin temperature and the volume will be in direct proportion when the pressure exerted on a sample of a dry gas is held constant.

### Which gas laws have an inverse relationship?

15 Gas Laws LumenLearning Boyle’s law describes the inverse relationship between the pressure and volume of a fixed amount of gas at a constant temperature. Apply Boyle’s law using mathematical calculations.

• According to Boyle’s law, an inverse relationship exists between pressure and volume.
• Boyle’s law holds true only if the number of molecules (n) and the temperature (T) are both constant.
• Boyle’s law is used to predict the result of introducing a change in volume and pressure only and only to the initial state of a fixed quantity of gas.
• The relationship for Boyle’s law can be expressed as follows: P 1 V 1 = P 2 V 2, where P 1 and V 1 are the initial pressure and volume values, and P 2 and V 2 are the values of the pressure and volume of the gas after change.

## What is direct relationship and inverse relationship?

Earth07: Direct, Inverse Direct relationship: A direct relationship means that both variables increase together or both decrease together. In a direct relationship, Y increases when X increases. On a graph, a direct relationship always has a positive slope.

### What is a direct and inverse relationship?

4. What is the difference between a direct and an inverse relationship? – A direct relationship, as opposed to an inverse relationship, exists when there is a positive correlation between two variables. In other words, if one variable increases then the other variable increases as well.

#### Which of the following gas properties best describe the relationship in Charles Law?

Summary – The volume of a gas is inversely proportional to its pressure and directly proportional to its temperature and the amount of gas. Boyle showed that the volume of a sample of a gas is inversely proportional to its pressure ( Boyle’s law ), Charles and Gay-Lussac demonstrated that the volume of a gas is directly proportional to its temperature (in kelvins) at constant pressure ( Charles’s law ), and Avogadro postulated that the volume of a gas is directly proportional to the number of moles of gas present ( Avogadro’s law ).

#### Which law best describe the relationship between pressure and volume?

Laws of Gas Properties – There are 4 general laws that relate the 4 basic characteristic properties of gases to each other. Each law is titled by its discoverer. While it is important to understand the relationships covered by each law, knowing the originator is not as important and will be rendered redundant once the combined gas law is introduced.

So concentrate on understanding the relationships rather than memorizing the names. Charles’ Law- gives the relationship between volume and temperature if the pressure and the amount of gas are held constant : 1) If the Kelvin temperature of a gas is increased, the volume of the gas increases. (P, n Constant) 2) If the Kelvin temperature of a gas is decreased, the volume of the gas decreases.

(P, n Constant) This means that the volume of a gas is directly proportional to its Kelvin temperature. Think of it this way, if you increase the volume of a gas and must keep the pressure constant the only way to achieve this is for the temperature of the gas to increase as well. Calculations using Charles’ Law involve the change in either temperature (T 2 ) or volume (V 2 ) from a known starting amount of each (V 1 and T 1 ): Boyle’s Law – states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. The reduction in the volume of the gas means that the molecules are striking the walls more often increasing the pressure, and conversely if the volume increases the distance the molecules must travel to strike the walls increases and they hit the walls less often thus decreasing the pressure. Avagadro’s Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure. Conversely if you cool the molecules down they will slow and the pressure will be decreased. To calculate a change in pressure or temperature using Gay Lussac’s Law the equation looks like this: To play around a bit with the relationships, try this simulation,

#### What is the relationship between Charles and Boyle’s law?

Charles’ law says that if the temperature of a gas doubles then its volume will also double if the pressure remains constant. Boyle’s law, conversely, says that if the pressure of the gas is doubled then its volume will become half of what it was if the temperature remains constant.
