What relationship does Avogadro law describe apex? What relationship does Avogadro law describe apex? Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules,

- This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
- What relationship does Boyle’s law describe? Boyle’s law is a connection between pressure and volume,
- It asserts that under constant temperature, the pressure of a specific quantity of gas is inversely proportional to its volume.

What is the relationship for the two variables in Charles Law? In Charles’ law, the relationship between Temperature (T) and Volume (V) is analyzed. The form of Charles’ law is: V = k*T, where k is a constant and the pressure is constant. In this equation the mass is constant and the air is confined to a compressible and expandable volume.

Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules, This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas,

- The law is approximately valid for real gases at sufficiently low pressures and high temperatures.
- The specific number of molecules in one gram- mole of a substance, defined as the molecular weight in grams, is 6.02214076 × 10 23, a quantity called Avogadro’s number, or the Avogadro constant,
- For example, the molecular weight of oxygen is 32.00, so that one gram-mole of oxygen has a mass of 32.00 grams and contains 6.02214076 × 10 23 molecules.

The volume occupied by one gram-mole of gas is about 22.4 litres (0.791 cubic foot) at standard temperature and pressure (0 °C, 1 atmosphere) and is the same for all gases, according to Avogadro’s law. The law was first proposed in 1811 by Amedeo Avogadro, a professor of higher physics at the University of Turin for many years, but it was not generally accepted until after 1858, when an Italian chemist, Stanislao Cannizzaro, constructed a logical system of chemistry based on it.

#### What relationship does Avogadro and law describe?

What relationship does Avogadro’s law describe? – A modern statement is: Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

#### What does avagadros law say about a gas at STP?

Avogadro ‘ s law states that the volume of a gas at constant temperature and pressure is directly proportional to the number of moles of gas present. It’ s mathematical representation follows:

#### How is Avogadro’s law used in everyday life?

How is Avogadro’s law used in everyday life? + Example states that the volume of a gas is directly proportional to the number of moles of gas. Here are some examples. As you blow up a basketball, you are forcing more gas molecules into it. The more molecules, the greater the volume. The basketball inflates. A flat tire takes up less space than an inflated tire, because it contains less air. Lungs expand as they fill with air. Exhaling decreases the volume of the lungs. A balloon filled with helium weighs much less than an identical balloon filled with air. Both balloons contain the same number of molecules. Helium atoms have lower mass than either oxygen molecules or nitrogen molecules in air, so the helium balloon is lighter. Hope this helps. : How is Avogadro’s law used in everyday life? + Example
