Answer 1

Hey mate,

Here's your answer.. ☺

a. The amount of water vapour in air is determined in terms of its Humidity.

b. If objects of equal masses are given

equal heat, their final temperature will

be different. This is due to difference

in their Specific Heat Capacity.

c. During transformation of liquid phase

to solid phase, the latent heat is Latent Heat of Fusion.

Hope it helps.
