State

At constant pressure, a fixed amount of gas has volume directly proportional to its kelvin temperature.

Show

A sealed balloon shrinks in a freezer and re-expands at room temperature, its volume tracking the kelvin temperature change.

Watch for

Cooled far enough, this proportionality would predict zero volume at absolute zero — real gases liquefy first.
