⚫Why do we feel cold, when we keep acetone and ether on our plam?

▶️We feel cold when we put some acetone on our hand because of latent heat of vaporisation.

▶️When it comes in contact with our skin, it absorbs heat energy from our palm.

▶️Because of the loosing of heat from our that part of the body, we feel cold as compared to other parts.

$\bf \huge \it{Hey \: User!!!}$

we know that evaporation causes cooling. this is all because of latent heat of vaporisation.

that's why some people sprinkle water in their surroundings during a hot sunny day.

the particles of the water absorb energy from the surrounding and this absorption of energy from the surrounding make the surface area cool.

for this reason people sprinkle water to cool the surroundings.

the same thing happens with acetone when it's kept on our palm. the particles of acetone gain energy from our palm and surroundings and then evaporates leaving our palm to feel cool.

that's why we feel cold when we keep acetone on our palm.
