How do lungs work according to Boyle’s law of gases? Explain.

Expert Solution

Boyle's law describe the relationship between Pressure(P) and Volume(V) of a gas. As per Boyles law, at a constant temperature, the product of Pressure and Volume is always constant.Numerically, it can be shown as-

PV = Constant or,

P1V1 = P2V2

Thus the law states that if Pressure increases then Volume must decrease and if Volume increases then Pressure must decrease i.e.vice-versa.

Now, coming to the functioning of lungs. Lungs play a crucial role in the breathing process of a living being. Breathing occus when there is a contraction or relaxation of muscles around the lungs which changes the total volume of air within the air passages inside the lungs. Thus, when the Volume of air in lungs changes, the Pressure of the air in lungs also changes as per the Boyle's Law. If the pressure is greater in the lungs than outside the lungs, the air rushes out ( as the volume decreases as per the law) and if the pressure is lesser inside the lungs, air rushes in. This is how lungs work.

Breathing is an application of Boyle’s law (Figure 10.8). As the diaphragm muscle beneath our lungs contracts, the pressure inside our lungs decreases causing air to rush into our mouth and nasal passages to fill the lungs. When the diaphragm muscle relaxes, it increases the air pressure causing air to be expelled from the lungs. A typical lung volume is 3.50 L. Air pressure inside the lungs changes by approximately 0.040 atm. A sample of air has a volume of...

According to Boyle’s law, for a certain gas, pressure an volume are inversely proportional: P = 800/V where V is measured in and pressure P in pounds per square inch. a) Find the rate of change of P when V=20 , and interpret its meaning (carefully state the units). b) Find the average rate of change of P when V changes from 20 to 25 . Compare your result with a).

The Boyle’s Law and the Gay-Lussac’s Law express experimental relationships between two of the three parameters characterizing the state of gas, the pressure, volume, and temperature, while the third is kept constant. For both laws state which parameters are variable and which is kept constant. The Boyle’s Law and the Gay-Lussac’s Law are special cases of a more general relationship called the ideal gas law. State the ideal gas law. Why do we use the absolute temperature (temperature in kelvins)...
