Question

A piece of ice of $100g$ in mass is kept at $0^{\circ }C$. The amount of heat it requires to melt at $0^{\circ }C$ is (take latent heat of melting of ice to be $333.6J/g$) ________.

• A. $750.6J$
• B. $83.4J$
• C. $33360J$
• D. $3.336J$

Answer 1

Answer: (C)

$33360J$

Heat required to melt the ice is,

$Q=m{L}_f=100\times 333.6=33360J$
