Questions & Step-by-Step Solutions

What is the term for the temperature at which a liquid's vapor pressure equals the external pressure?
  • Step 1: Understand what vapor pressure is. It is the pressure exerted by a vapor in equilibrium with its liquid or solid form.
  • Step 2: Know that every liquid has a vapor pressure that increases with temperature.
  • Step 3: Learn that external pressure is the pressure surrounding the liquid, like atmospheric pressure.
  • Step 4: Realize that when the vapor pressure of the liquid becomes equal to the external pressure, the liquid starts to boil.
  • Step 5: Conclude that this specific temperature is called the boiling point.
