Question

Latent heat of vaporisation of two liquids is 100 j/kg and 150 j/kg respectively. Which liquid will produce more cooling effect and why

Answer 1

Answer:

100 j/kg will produce more cooling because it releases less latent heat of vaporization as it contains only boiling heat not hidden heat.

Answer 2

Answer:

150 j/kg

Explanation:

let us keep 100 j/kg as liquid A and 150 j/kg as liquid B.

Liquid B produces more cooling effect than the liquid A because Liquid B takes the heat from the surrounding for vaporization.so the answer is 150 j/ kg
