4. The other phase change that can happen is liquid to gas. Similar to the phase change of solid to liquid, the temperature of the system does not change. All of the energy goes into the phase change. Only now instead of the latent heat of fusion, we have the latent heat of vaporization: Q = mly How much heat must be added to 3.8 kg (1 gallon) of water for half of it to be changed into gas? The...
