Solution

The correct option is B
High latent heat of fusion

The reason is that ice has a high latent heat of fusion (equal to 336000 $J k g^{- 1}$ ). It is due to this fact that it changes into the water slowly as it gets heat energy from the sun.

Q. The boiling point of water is low at high altitude explain.

Heat is supplied at the same rate to equal masses of ice and water at the melting point (MP) of ice. Calculate the ratio of the time required to melt the ice and to bring the water to its Boiling Point. [Given that specific heat capacity of water = 4.2 J/g^oC, Specific latent heat of ice = 336 J/g]
