Question

Why do we feel feel cool when we apply nail polish on nails?

Answer 1

Once the polish is applied the solvent ( liquid) portion is evaporated leaving the pigment and other solid component on the nail.

Just like when we are sweaty and feel cool in the wind ( the sweat evaporates and the process makes us feel cool).

Why do we feel feel cool when we apply nail polish on nails?

Because nail polish remover takes latent heat from our palm and hence we feel cool.

• Evaporation causes cooling as liquid changes to water vapour by absorbing heat from the surface and leaving the surface cool.
