the diaphragm and rib muscles contract. From which structures do oxygen molecules move from the lungs to the blood? TermWhich statement is correct? In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells After blood becomes oxygenated, it returns to the heart, and is then pumped to body cells.

What description accurately describes Boyle’s Law?

Clinical Significance – At birth, newborns are born with no air within their alveoli; thus, the volume is zero. The compliance (elasticity of lung tissue) is low at birth. Therefore, the effort to create negative intrapleural pressure during the initial breaths is high; however, the lungs fill with air and become more compliant with successive breaths.

  1. As the lungs become more compliant, the newborn’s lungs will follow Boyle’s law of the inverse relationship of pressure and volume.
  2. Pneumothorax is a clinical condition that can either be primary (typically from trauma) or secondary (patient has a predisposing condition such as COPD).
  3. Boyle’s law dictates how air draws into the lungs.

As the intrathoracic pressure becomes increasingly negative, the intra-alveolar pressure decreases below atmospheric pressure, causing air to flow into the lungs. In a pneumothorax, there is increased pressure within the intrapleural space, thus causing the need for an increased force to create enough negative pressure for air to come into the lungs.

Boyle’s law also applies when using a medical syringe. When the cylinder on the syringe is empty, it is said to be in a neutral state as there is no air in the syringe. As one pulls back on the plunger, the volume in the cylinder increases, therefore by Boyle’s law, the pressure decreases. The liquid is thus drawn into the cylinder to balance the pressure within the syringe and outside of the syringe.

SCUBA divers must be cognizant of Boyle’s law as they descend and ascend to great depths. As a diver descends in the water, the pressure on the person’s lungs increases, and therefore according to Boyle’s law, the volume of air inside the lungs must decrease.

Which of the following best describes how Boyle’s law relates?

Which of the following best describes how Boyle’s law relates to the mechanics of breathing? If lung volume decreases, intrapleural pressure increases, forcing air into the lungs.

Which of the following is true regarding Boyle’s Law?

The correct option is A At a given temperature, pressure of a given mass of gas is inversely proportional to its volume.

Which statement accurately describes how Boyle’s law relates to respiration?

Answer and Explanation: The answer is Boyle’s Law: Pressure changes caused by changes in lung volume allow air to enter the lungs during inspiration and air to move out of the lungs during expiration. This law is about the relationship between volume and pressure in a gas at a constant temperature.

Which statement is a description of Boyle’s law quizlet?

Boyle’s law states that when the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

Which is a statement of Boyle’s law quizlet?

Which is a statement of Boyle’s law? The volume of a fixed quantity of gas maintained at constant temperature is inversely proportional to the pressure.

Which of the following describes the Boyle’s law equation *?

Boyle’s Law Boyle’s Law is a basic law in chemistry describing the behavior of a gas held at a constant temperature. The law, discovered by Robert A. Boyle in 1662, states that at a fixed temperature, the volume of gas is inversely proportional to the pressure exerted by the gas.

In other words, when a gas is pumped into an enclosed space, it will shrink to fit into that space, but the pressure that gas puts on the container will increase. Perhaps a more straightforward way is to say Boyle’s law is the relationship between pressure and volume. Mathematically, Boyle’s law can be written as pV=k, where p is the pressure of the gas, V is the volume of the gas, and k is a constant.

An example of Boyle’s law in action can be seen in a balloon. Air is blown into the balloon; the pressure of that air pushes on the rubber, making the balloon expand. If one end of the balloon is squeezed, making the volume smaller, the pressure inside increased, making the un-squeezed part of the balloon expand out.

Which is a statement of Boyle’s law the volume?

The Relationship between Pressure and Volume: Boyle’s Law – As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart. Which Of The Following Descriptions Accurately Describes Boyle’S Law Figure \(\PageIndex \): Boyle’s Experiment Using a J-Shaped Tube to Determine the Relationship between Gas Pressure and Volume. (a) Initially the gas is at a pressure of 1 atm = 760 mmHg (the mercury is at the same height in both the arm containing the sample and the arm open to the atmosphere); its volume is V,

  1. B) If enough mercury is added to the right side to give a difference in height of 760 mmHg between the two arms, the pressure of the gas is 760 mmHg (atmospheric pressure) + 760 mmHg = 1520 mmHg and the volume is V /2.
  2. C) If an additional 760 mmHg is added to the column on the right, the total pressure on the gas increases to 2280 mmHg, and the volume of the gas decreases to V /3 (CC BY-SA-NC; anonymous).

The Irish chemist Robert Boyle (1627–1691) carried out some of the earliest experiments that determined the quantitative relationship between the pressure and the volume of a gas. Boyle used a J-shaped tube partially filled with mercury, as shown in Figure \(\PageIndex \).

In these experiments, a small amount of a gas or air is trapped above the mercury column, and its volume is measured at atmospheric pressure and constant temperature. More mercury is then poured into the open arm to increase the pressure on the gas sample. The pressure on the gas is atmospheric pressure plus the difference in the heights of the mercury columns, and the resulting volume is measured.

This process is repeated until either there is no more room in the open arm or the volume of the gas is too small to be measured accurately. Data such as those from one of Boyle’s own experiments may be plotted in several ways (Figure \(\PageIndex \)).

  • A simple plot of \(V\) versus \(P\) gives a curve called a hyperbola and reveals an inverse relationship between pressure and volume: as the pressure is doubled, the volume decreases by a factor of two.
  • This relationship between the two quantities is described as follows: \ Dividing both sides by \(P\) gives an equation illustrating the inverse relationship between \(P\) and \(V\): \ or \ where the ∝ symbol is read “is proportional to.” A plot of V versus 1/ P is thus a straight line whose slope is equal to the constant in Equations \(\ref \) and \(\ref \).

Dividing both sides of Equation \(\ref \) by V instead of P gives a similar relationship between P and 1/ V, The numerical value of the constant depends on the amount of gas used in the experiment and on the temperature at which the experiments are carried out. Which Of The Following Descriptions Accurately Describes Boyle’S Law Figure \(\PageIndex \) : Plots of Boyle’s Data. (a) Here are actual data from a typical experiment conducted by Boyle. Boyle used non-SI units to measure the volume (in.3 rather than cm 3 ) and the pressure (in. Hg rather than mmHg). (b) This plot of pressure versus volume is a hyperbola.

  1. Because PV is a constant, decreasing the pressure by a factor of two results in a twofold increase in volume and vice versa.
  2. C) A plot of volume versus 1/pressure for the same data shows the inverse linear relationship between the two quantities, as expressed by the equation V = constant/ P (CC BY-SA-NC; anonymous).
