Questions & Step-by-Step Solutions

What is the effect of increasing pressure on the boiling point of a liquid?
  • Step 1: Understand that boiling occurs when a liquid turns into vapor.
  • Step 2: Know that boiling happens when the vapor pressure of the liquid equals the surrounding pressure.
  • Step 3: Realize that increasing the pressure around a liquid makes it harder for the vapor to escape.
  • Step 4: Conclude that to reach the point where the vapor pressure equals the higher pressure, the temperature of the liquid must increase.
  • Step 5: Therefore, increasing pressure raises the boiling point of the liquid.
