Question

why do surgeon apply Ether on the part of our body which is to be operated

Answer 1

Surgeons apply ether on the part of the body to be operated because ether is a volatile substance and its boiling point is too low.This makes evaporation of ether easier by absorbing energy from the body in the form of heat and makes the part feel cool.Hence, the patient feels lesser pain in the part to be operated.

Answer 2

"The surgeon applies Ether on the part of our body to be operated during minor surgery to reduce pain.

On the part of our body, the surgeon applies Ether to be operated during minor surgery because ether is a volatile substance that is its boiling point is low. So it evaporates faster and because of evaporation, the energy lost by the surrounding particles makes the area cool and leaves it numb, i.e., the patient does not feel much pain."
