Question

Write the approximate value of specific latent heat of ice.
(A) $136 J{g^{-1}}$
(B) $236 J{g^{-1}}$
(C) $336 J{g^{-1}}$
(D) $436 J{g^{-1}}$

Answer 1

Hint
The specific latent heat of ice is $334{\rm{\;J}}{{\rm{g}}^{ - 1}}$ and this implies that out of the options given, the approximate value of specific latent heat of ice is $336{\rm{\;J}}{{\rm{g}}^{ - 1}}$

Complete step by step answer
When the phase or physical state of a substance is changed to the other state such that there is no change in the temperature of the substance, then the amount of heat absorbed or released during the process is referred to as latent heat. The amount of energy required or spent in the conversion of phase state of a unit mass of a substance of another state is called specific latent heat. The specific latent heat of ice is the amount of energy spent in the melting of one gram of ice such that $334$ $J$ is spent in the melting of one gram of ice. This implies that the value of specific latent heat of ice is $334{\rm{\;J}}{{\rm{g}}^{ - 1}}$
Therefore, (C) $336{\rm{\;J}}{{\rm{g}}^{ - 1}}$ is the correct answer.

Note
This latent heat of ice can also be referred to as heat of fusion of ice. Both are the same terms that are associated with the change in the physical state of a solid into liquid i.e. with the melting of ice.
