The behaviour of gases is described in terms of the kinetic theory, which considers the motion of molecules in the gas. The gas law links pressure, volume and temperature.

If the temperature of a fixed mass of gas increases, what happens to the average kinetic energy of the particles in the gas?

It decreases

It remains the same

It increases

What is in Kelvin?

What temperature scale must be used in calculations relating to the Gas Laws?

Centigrade scale

Farenheit scale

Kelvin scale
