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.

Text Solution

Verified by Experts

Yes, because steam at `100^@C` gives out its latent heat of vapourization to condense the water at the same temperature of `100^@C`.
