• Why does your skin become colder? when a few drops of spirit on your palm using a droper.
Answers
HERE IS UR ANSWER ⤵⤵
➡If we pour few drops of Spirit in our palm, the skin becomes colder because if it is poured on the palm , it readily changes into vapour or evaporates. For this , it needs some energy which is taken from the palm.
The temperature of the palm gets lowered and we gets a cool sensation.

Answer:
Spirit transforms when it takes heat from the surface of the hand.
Explanation:
When a substance in the liquid state receives energy, it transforms into a vapour and the energy received during this transformation is known as the heat of vaporization. We experience a cold sensation as a result of spirit absorbing the thermal energy from the surfaces of our hands, which causes it to evaporate.
The skin gets cooler if we put a few droplets of spirit in our palm because as it touches the palm, it quickly turns to vapour / evaporates. It requires some energy for this, which is extracted from the palm.
If we drop a little methylated spirit on our hand, it will quickly evaporate, leaving our hand feeling chilly. Our hand provides the energy required by the methylated spirit particles, reducing our hand's molecules with much less energy and making them cooler.
The methylated spirit will chill your skin down even if it is at the same temp as your skin. The methylated spirit dries out rather quickly. It absorbs the energy from its surroundings, especially your hand, as it evaporates. The Heating Value of Vapourisation is the name for the amount of energy needed for something to evaporate.
