Why does our palm feel cold when we put some acetone or petrol or perfume on it?

– Refreshing Coolness: Acetone, petrol, and perfume create a sensation of coolness when in contact with the skin due to their rapid evaporation.
– Low Boiling Points: These substances have low boiling points, causing them to transition swiftly from a liquid to a gas upon contact with the warmth of the skin.
– Heat Absorption: Evaporation of these substances is an endothermic process, meaning it absorbs heat from the skin to convert into a gas, leading to a decrease in skin temperature.
– Intensified Evaporation: Their high volatility further amplifies the speed of evaporation, enhancing the cooling effect experienced on the skin.
– Caution Needed: Prolonged contact with these substances can potentially cause skin irritation or dryness, necessitating care and moderation in their usage to avoid adverse effects.
