How hot would a 2.3 L balloon have to get to expand to a volume of 3.0 L, assuming the initial temperature of the balloon is 24°C, and that the pressure inside the balloon remains constant?
The temperature needs to be 390 K.
This is an example of Charles' law, which states that the volume of a gas held at constant pressure varies directly with the Kelvin temperature. The equation for this law is:
Rearrange the equation to isolate
