Question

Why evaporation causes cooling

Answer 1

The remaining particles in the liquid have a lower average kinetic energy than before, so the liquid cools down as evaporation happens. This is why sweating cools you down. The sweat absorbs energy from your skin so that it can continue to evaporate.

Answer 2

Heya friend,

1) Evaporation causes cooling. Why?

1) Evaporation causes cooling because as we know that evaporation is a surface phenomenon. The particles at the surface of the substance takes heat from the particle's beneath it and then vapour up and as the particles take the heat from the particle's beneath them, heat is transferred and the particle's beneath became coo. In this way evaporation causes cooling.

In case of nail polish remover, or Sanitizer, when we apply it on our hand , we feel cool. Why? This is because the particle of remover/Sanitizer takes the heat from our hand and then our skin becomes cool.



Hope it helps..!!!
