Question

a). "Evaporation cause cooling" explain the reason for this effect

b). Explain two example from our daily life where we fell the effect of cooling during evaporation​

Answer 1

Evaporation causes cooling because the process requires heat energy. The energy is taken away by the molecules when they convert from liquid into gas, and this causes cooling on the original surface.

1) Hot tea gets cool over time due to evaporation - hot molecules on the surface gets evaporated taking away heat with them.

2) Wet clothes dry in sun due to evaporation - the water in wet clothes takes heat energy from sun and gets evaporated
