Question

If the latent heats of vaporisation of two liquids A and B are 200J/kg^-1and 100 J/kg ^-1 respectively, then which liquid would produce more cooling?​

Answer 1

Answer:

as the liquid B has less latent heat of vaporisation the heat require to vaporize would be less compare to A

and for cooling heat heat is removed from the system and that heat removed will be equal to heat gained while vaporization according law of conservation of energy

so it will give more cooling effect

that is liquid B

hope so helpful .
