changing from a liquid to a vapor. The vapor then rises, condenses on a heat exchanger, and releases the heat before returning to a liquid state. Two-phase cooling is more efficient in heat transfer due to the latent heat of vaporization but requires a complex system design to ...
a lake, river, or ocean to allow some of its water molecules to switch from a liquid and be released as a water vapor into the air, heat from the sun must be present to initiate the process. A change in energy or pressure is always required from some source for this process to ...
