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 ...

The initial layer of ice acts as an insulating barrier, slowing further heat loss from the water below. As water freezes, it releases latent heat into the surrounding environment, a process that ...
