Diffusion of Gases

Question 1

What is the kinetic energy of a gas dependent on?

Answer 1

The KE of a gas is directly proportional to its absolute temperature

Question 2

What is a compressible fluid?

Answer 2

A fluid that can change in volume (volume is inversely proportional to pressure)
Boyle’s Law (above) only applies for gases not too dense and not too close to boiling point

Question 3

What is the standard temperature and pressure for the Ideal Gas Law?

Answer 3

temperature = 0 degrees C = 273.15K
pressure = 1 atm = 101.3 kPa
volume = 22.4 L

Question 4

How do you calculate osmotic pressure for an ideal gas?

Answer 4

Π = (n/V) * RT

Question 5

What is Henry’s Law?

Answer 5

Equilibrium concentration of dissolved gas is proportional to partial pressure of the same gas, present in the gas above the liquid

Question 6

What is dynamic equilibrium?

Answer 6

When the same number of gas molecules are leaving and entering the liquid state
