उत्तर
- When we put some acetone or petrol or perfume on our palm, it evaporates.
- During evaporation, particles of the liquid absorb energy from the surrounding or the surface of the palm to compensate for the loss of energy, making the surroundings cool.
- Hence, our palm feels cold when we put some acetone or petrol or perfume on it.
