Question

Why the particles of steam possess more energy than watet at the same temperature?

Answer 1

because steam is hot so it goes Ups and applies more pressure and water is densier as well as heavy so its force is applied down

Answer 2

The particles of steam possess more energy than water at the same temperature because of the latent heat is vapourisation.
The latent heat of vapourisaion is the heat required to convert 1 l of water into water vapour.
The steam particles possess more energy because it has more latent heat as compared to water. Also it gives more severe burns.
Hope this helps...
