Question

Give reason - (1) A sponge can be compressed easily still it is called solid.


(2) Water vapour has more energy than water at same temperature. ​

Answer 1

Answers:

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.

Answer 2

Answer:

a sponge can can be compressed easily and called solid because it moleculs have some gaps between them
