Question

why does our plam fell cold when we put alcohol or perfume on it?

Answer 1

The latent heat of alcohol or perfume is larger .So when we keep it on our Palm it takes the heat from its surrounding that is from our palm to evaporate. That's why our palm feels cool.

Answer 2

When we put some acetone or perfume on our palm then the particles gain energy from our palm or surrounding and evaporate causing the palm cool
