Latent heat of fusion of two liquids A and B is 100 j/kg and 150j/kg respectively. Which one will produce more cooling. Effect and why?

Open in App

Solution

It should be Latent Heat of Vaporisation. Because, it is the vaporisation that causes cooling. Liquid B will produce more cooling effect, because it has a higher latent heat of vaporisation( when compared to liquid A). Therefore, it absorbs more heat than Liquid A( whose latent heat of vaporisation is lesser).

Why is the latent heat of fusion of ice i.e 3.34×10⁵J/kg less than the latent heat of vapourisation i.e 22.5×10⁵J/kg? Particles of solids are more tightly packed than liquids so literally the should require more energy for separation than liquids.

Q. A container contains

0.25 k g

of a liquid at its boiling temperature.
If the latent heat of fusion for the liquid is

500 J o u l e s / k g

and the latent heat of vaporization for the liquid is

1000 J o u l e s / k g

, how much heat must be added to the liquid to boil all of the liquid away?
