any 10 appliances that work on the concept of latent heat of evaporation?
Refrigerators - The cooling effect of fridges can be provided by expanding a refrigerant (often a hydrocarbon) through a valve, which causes it to become cold and effectively suck any heat away from the inside of the fridge. Heat Exchangers - Some heat exchangers operate via the condensation of a warmer fluid onto a pipe which contains a colder fluid, effectively transferring the heat of vaporisation. Human Body - The human body effectively cools itself down via evaporation of water from the skin's surface. As the water evaporates, it draws energy from the body and thus produces a cooling effect.
