The physical meaning of the specific heat of fusion λ: this is the amount of heat that must be communicated to 1 kg of a substance at the melting temperature in order to transfer it from a solid state of aggregation to a liquid state.
The physical meaning of the specific heat of crystallization λ: this is the amount of heat that is released during the transition of 1 kg of a substance at the melting point of their liquid state of aggregation into a solid state.
This is one and the same quantity, which is called differently, only depending on
λ = 110 kJ / kg, means that during the crystallization of 1 kg of a substance, heat energy Q = 110 kJ is released.
Upon crystallization of 2 kg of platinum, 22 kJ of heat will be released.
