Boyle's law

Question 1

Gas follows its

Answer 1

pressure gradient

Question 2

Changes in ___________ produce the flow of air ____________

Answer 2

intra-alveolar pressure

into and out of the lungs

Question 3

If this pressure is _____ than atmospheric pressure, air enters the lungs. If the opposite occurs, air exits from the lungs.

Answer 3

less

Question 4

Boyle’s law states that

Answer 4

at any constant temperature, the pressure exerted by a gas varies inversely with the volume of a gas.

so:
Volume = 2
pressure = 1/2

> decreasing volume- increases collisions = increased
pressure
assumes temp and num of gas molecules remains
constant

Question 5

Respiration:

Answer 5

Δvolume -> Δpressure gradients-> control and direction of airflow

Question 6

Other gas laws:

Answer 6

1. Dalton’s law:
   Total pressure of a mixture of gases is the sum of the pressures of the individual gases
2. Gases, singly or in a mixture, move from area of higher pressure, to areas of lower pressure
