Question

Give reasons : i) a sponge can be pressed easily; still it is called a solid. Ii) water vapours have more energy than water at same temperature

Answer 1

Answer:

it is nit called solid

Explanation:

the air is filled in the sponge is come out when we press it is comptesibility

Answer 2

i) A sponge can be pressed easily still it is called a solid

A sponge can be compressed easily, but it can be considered as a solid. Because the sponge has lots of minute holes that is filled up with air. When we compress sponge, the air is expelled out.

ii) water vapours have more energy than water at the same temperature.

When water converts into water vapour it absorbs the latent heat of vaporisation. But water in the liquid state does not contain the latent heat of vaporization. Hence water vapour has more energy in the form of latent heat than water at the same temperature.
