What will happen if you pour some acetone on your palm? 

The correct answer is It will cause the palm to feel cool.

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.
