The volume of a gas is directly proportional to the number of moles at constant temperature and pressure.

The volume of a gas is inversely proportional to the number of moles at constant temperature and pressure.

The pressure of a gas is directly proportional to the number of moles at constant volume and temperature.

The temperature of a gas is directly proportional to the number of moles at constant pressure and volume.

The sum of the partial pressures of each gas

The product of the partial pressures of each gas

The difference between the largest and smallest partial pressures

The average of the partial pressures of each gas

Gases consist of large numbers of molecules in continuous, random motion.

The combined volume of all the molecules of the gas is negligible relative to the total volume.

Gas molecules are strongly attracted to each other.

Attractive and repulsive forces between gas molecules are negligible.

Gases expand to fill their containers, are highly compressible, and have low densities.

Gases have fixed shapes and volumes like solids.

Gases are composed mainly of metallic elements.

Gases cannot form mixtures with other gases.

It increases over time.

It decreases over time.

It remains the same.

It fluctuates randomly.
