Question

State two advantages of the high specific latent heat capacity of steam, which is about 226 × 10⁴ J/kg?

Answer 1

(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.
