Question

Give reason c) if we put acetone or sprite in our plam feel cool

Answer 1

When we put acetone on our hands it starts to vaporise or evaporate at a fast rate. This increases the liquid molecules around it in vapour phase thus our palm feel cold. Acetone has very low boiling temperature. When we put some acetone on our palm the particles of it gain energy from our palm and evaporate quickly which causes cooling.
