Ideal Gases

Question 1

Define the mole.

Answer 1

1 mole of particles is equivalent to the number of Carbon-12 molecules there are in 12g of Carbon-12***. This is equivalent to Avogadro’s Constant number of particles.

Question 2

Define Avogadro’s Constant.

Answer 2

The number of particles in 1 mol(e), NA = 6.02 x10^23.

Question 3

State Boyle’s Law.

Answer 3

For a fixed mass of an ideal gas at a constant temperature, its pressure is inversely proportional to its volume.

Question 4

Define Molar Gas Constant.

Answer 4

The constant in the equation of state of an ideal gas, R = 8.31 J K-1 mol-1.

Question 5

Define Root mean square speed.

Answer 5

The square root of the mean square speed.
