Question
Explain the different example caused due to cooling by evaporation
Open in App
Solution
Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surrounding cool.
Ex : when we spray a deo on our hand.
Ex 2 : Aetone
Reason for the above examples : the deo and the nail poslish romover are volatile substance. they absorb latent heat of vaporisation from aur hand and gets converted rapidly into gaseous form. henece we feel cold.
