Answer to Question #133771 in Molecular Physics | Thermodynamics for joseph Mathew

Question

What is the specific latent heat of a
0.75kg object that transfers 251kJ during a change of state?

Answer 1

Latent heat is the energy per unit of mass that is absorbed or released during a change of state. Therefore,

$L=\frac{Q}{m}=\frac{251kJ}{0.75kg}=335\frac{kJ}{kg}=335\frac{J}{g}$

Answer: $335\frac{J}{g}$
