Chem Final

A flask containing molecules of gas A and a separate flask containing the molecules of gas B are both at the same temperature. Gases A and B must have equal

Average kinetic energies

Which gas would have the slowest rate of diffusion when all of the gases are held at the same temperature and pressure?

CO2

As the pressure on a sample of a gas increases at constant temperature, the volume of the gas

Decreases

The volume of a given mass of an ideal gas at constant pressure is

Directly proportional to the Kelvin temperature

As the temperature of a sample of a gas increases at constant pressure, the volume of the gas sample

Increases

Which graph best represents how the volume of a given mass of a gas varies with the pressure exerted on it at a constant temperature?

Straight horizontal line

At constant pressure, which graph shows the correct relationship between the volume of a gas(V) and its absolute temperature(T)?

Straight increase left to right
