Why can liquid boil at a low pressure?


Sagot :

Final answer:

Liquids boil when their vapor pressure equals the external pressure, enabling them to boil at lower temperatures under reduced pressure.


Explanation:

Liquids boil when their vapor pressure becomes equal to the external pressure. If the applied pressure is reduced, the boiling point of the liquid decreases. Lowering the pressure means a lower vapor pressure is required for boiling, allowing the liquid to boil at a lower temperature.
