Question

Which contains more heat, 1 kg of water at 100&#xB0;C or 1 kg of steam at 100&#xB0;C? Give reason for your answer.

1 Kg of steam at 100°C has more heat than water at the same temperature because when water changes into steam, it absorbs latent heat, but when steam condenses to form water, an equal amount of latent heat is given out.
