Question 226

The specific latent heat of fusion of solid X is greater than that of solid Y.

What does this statement mean?

A

Less energy is needed to raise the temperature by 1 ∘C1\ ^\circ\text{C}1 ∘C of unit mass of solid X than unit mass of solid Y.

B

Less energy is needed to melt unit mass of solid X than unit mass of solid Y at their melting points.

C

More energy is needed to raise the temperature by 1 ∘C1\ ^\circ\text{C}1 ∘C of unit mass of solid X than unit mass of solid Y.

D

More energy is needed to melt unit mass of solid X than unit mass of solid Y at their melting points.
