Question

25 kg of a solid requires 8550 j of heat to melt. calculate the latent heat

Answer 1

Latent heat is the amount of heat needed by 1kg of material at its melting point.

Heat needed by 25kg of the solid = 8550 J

Heat needed by 1 kh of the solid = 8550/25 = 342 J/kg

Latent heat of fusion of the solid is 342 J/kg
