Key Points
- Acetone is a volatile and flammable liquid.
- When acetone is poured on the skin, it rapidly evaporates due to its low boiling point.
- This evaporation process requires energy in the form of heat, which it draws from the skin.
- The heat is taken away from the skin, causing the skin to cool down.
- This is similar to the cooling effect experienced when sweat evaporates from the skin.
Additional Information
- Heat Transfer
- The principle behind the cooling effect is related to heat transfer, where heat energy is transferred from the skin to the evaporating liquid.
- When liquids evaporate, they absorb heat energy from their surroundings.
- Evaporation Process
- Evaporation is a process where molecules transition from the liquid phase to the gas phase.
- This process occurs at temperatures below the boiling point of the liquid.
