Question

It becomes bitterly cold when ice on the hills starts melting because:

Options

• ice has the highest heat capacity of fusion of 336 Jg⁻¹

• every gram of ice which melts takes 336 J of heat energy from atmosphere.

• Ice has the highest heat capacity of fusion of 336 Jg⁻¹, and every gram of ice that melts takes 336 J of heat energy from the atmosphere.

• none of these

Answer 1

Ice has the highest heat capacity of fusion of 336 Jg⁻¹, and every gram of ice that melts takes 336 J of heat energy from the atmosphere.

Explanation:

Ice has a high specific latent heat of fusion, with a value of 336 Jg⁻¹. As ice melts, it absorbs this heat from the surroundings, making the air colder.
