प्रश्न
If, in a central heating system, steam enters a radiation pipe at 100°C and water leaves the radiation pipe at 100°C, can this radiation pipe heat a room? Give an explanation for your answer.

उत्तर
Yes, because steam at 100°C gives out its latent heat of vaporisation to condense to water ut the same temperature of 100°C.
