$<b>Sponge is a solid but compressible. Give reason</b>$

$\huge\mathbb\purple{Answer}$

➨Sponge is a solid but it can be easily compressed because it has minute holes in which air is trapped. When we press the sponge , the air is expelled out and we are able to compress it.

$<b>Why do we see water droplets on outer surface of glass containing ice cold water?</b>$

$\huge\mathbb\purple{Answer}$

➨The water vapour present in air touches the cold surface of glass. They lose their energy and get converted to water. These appear as water droplets outside the glass .
