# How would the volume evolve if a quantity of gas enclosed in a piston were heated?

What do you think would happen? And you can do the experiment by placing an inflated balloon under a light source for 5 minutes.

#### Explanation:

Charles' law states that at constant pressure, the volume is directly proportional to the $\text{Absolute Temperature}$, i.e. VpropT; n, and P constant.

Since $V = k T$ under these conditions, an increase in temperature will result in an increase in volume.
