In cold air, the kinetic energy is less and so the speed is less. When speed is less, the particles are more closer.
In hot air, kinetic energy is high and so the speed of individual particls are high. WHen speed is high particles are further apart. Now can you work out the answer?

Okay so in cold air particles are travelling slow, and in hot air particles are travelling fast.
Now imagine there is a room with people walking very slowly and a room where people are walking very fastly.
Which room have less people per unit area?
