Question

Explain, why steam pipes warm a building more effectively than hot water pipes in cold countries?

Answer 1

1. Water at a temperature of ${100}^{°}\text{C}$ absorbs latent heat of vaporization to transform to steam at ${100}^{°}\text{C}$.
2. Hence, steam at ${100}^{°}\text{C}$contains more energy than water at ${100}^{°}\text{C}$.
3. As a result, steam pipes can warm a building more effectively.
