Answer:
Ether is a volatile substance and to change from the liquid state to the vapor state, it requires latent heat of vaporisation. Ether takes up this heat of vaporisation from the portion of skin it is sprayed on. The energy lost by the particles from the affected area makes the area cool and leaves it numb i.e. the patient doesn't feel much of pain.
