Jan 23, 2017

Have you never poured liquid nitrogen onto a balloon.......?

#### Explanation:

The volume of the balloon decreases markedly.

This is a consequence of $\text{Charles' Law}$, $V \propto T$ for a given quantity of gas, where $T$ is the $\text{Absolute Temperature}$.

Given Charles' Law, for a given quantity of gas:

${V}_{1} {T}_{1} = {V}_{2} {T}_{2}$.......................
