Question
Explain why: Heating systems based on circulation of steam are more efficient in warming a building than those based on circulation of hot water.

Answer

A heating system based on the circulation of steam is more efficient in warming a building than that based on the circulation of hot water. This is because steam contains surplus heat in the form of latent heat (540 cal/ g).
