What is the specific latent heat of fusion for a substance that takes 550 kj to melt 14 kg at 262 k? answers

Specific latent heat of fusion of a substance is the heat required to transform 1 kg of a substance from solid state to liquid state at a particular temperature.

Heat required to melt 14 kg substance = 550 kJ

Mass of the substance = 14 kg

Calculating the specific latent heat of fusion:

or

Therefore, the specific latent heat of fusion is 39.3 kJ/kg or 39.3 J/g
