Question

Write four advantages of high latent heat of fusion of a substance

Answer 1

Answer:

(i) The main advantage of the high specific latent heat capacity of steam is in room heating in cold countries. The steam generated in the boiler is passed through pipes in radiators fixed within the building.

(ii) In thermal power station, steam is used as a medium for converting the chemical energy of coal to electric energy. Every gram of steam supplies a great amount of heat energy of about 2260 joule.

Answer 2

The latent heat of fusion and vaporization both involve the heat required to change the state of a substance without a change in temperature. In the case of the latent heat of fusion it is the heat required to change a substance from a solid (ice) to a liquid (water) or vice versa while the latent heat of vaporization from a liquid (water) to a gas (steam) or vice versa.
