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 system uses ice or ice slurry as the heat source and ... effective with water as the heat source due to water's high latent heat of fusion, enabling substantial energy absorption with low ...

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 ...
