Question

comment on the fallowing statements:
evaporation causes cooling
Rate of evoparation of an aques solution decreases
with increase in humidity
sponge though compressible is a solid​

Answer 1

Answer:

I don't know this answer

Answer 2

I) evaporation causes cooling because when the liquid state gets converted into gaseous state the surface onto which evaporation takes place gets cooled due to the latent heat of vaporisation of water.

2) when the humidity in air increases then the rate of evaporation decreases as the amount of water vapour in the air is already high so the air is not able to hold more water vapour.

3) sponge have tiny holes in which air is trapped when we press it the air get expelled out of the tiny holes by which we are able to compress it.
