13.9 Specific latent heat of vaporisation (kJ/kg) 213 An input of 334,000 joules (J) of energy is needed to change 1 kg of ice into 1 kg of water. The same amount of energy needs to be taken out ...

The temperature stays the same when a solid is melting or a liquid is boiling during a change of state, even though heat energy is being absorbed. The specific latent heat of a substance is a ...

When water melts from solid ice to liquid, for example ... which uses energy referred to as latent heat. If that vapor turns back into liquid, the way it does when it meets a cold can in warm ...
