Answer 2

The decrease in the size of matter on cooling is called​ contraction.

Explanation:

• Cooling of a matter decreases the speed of the molecules present in it. As a result attractions between molecules increases and bring the molecules closer to each other.
• Which eventually decreases the volume of matter and hence the size of matter.

• For example, LPG, CNG and other gases, as cooling of gas compresses it, which makes it easier packing it into smaller containers for transport and other uses.
