Question

The snow on the mountain does not melt all at once when it is heated by the sun because it

• A. Becomes very hard
• B. reflects most of the heat from the sun
• C. has a low specific heat capacity
• D. has a high latent heat of fusion

Answer 1

The correct option is D has a high latent heat of fusion

At mountain, there is very large amount of snow i.e. $m$ is very very high.

And for melts of ice, latent heat of fusion is required.

Latent heat of fusion = mass$\times L_f$

And since very very large mass is present so very high amount of heat is required which can't be delivered by sun at once.
