The latent heat of fusion of a solid ‘ substance of mass “m” is L. The required amount of heat to change solid phase to liquid phase is ……………… cal.

Correct option is  A) Both are true

1. Latent heat of fusion: The quantity of heat required to convert unit mass of a substance from its solid state to the liquid state, at its melting point, without any...

1. The energy required to completely separate the molecules or atoms in liquids is greater than the energy needed to break the rigidity (rigid bonds between the molecules or atoms)...

Mass (m) = 2 kg = 2 × 103 g. latent heat of fusion for ice (L) = 80 cal/g. To find: Heat energy (Q) Formula: Q = mL From formula, Q = 2 × 103 ×...

 Q = mL so, L = Q/m. Hence, the correct option is (B) Q/m

A) 80 cal/gm

Correct option is  B) J/Kg

Correct option is  B) 1 g

Correct option is  C) freezing
