Question
How can you increase the boiling point of water?A.By lowering the pressure of the waterB.By increasing the air pressure above the waterC.By increasing the volume of the waterD.By lowering the air temperature above the water
Solution
The boiling point of water can be increased by increasing the air pressure above the water. Here's a step-by-step explanation:
-
The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure.
-
When the atmospheric pressure increases, the vapor pressure needed for a liquid to boil also increases.
-
Therefore, by increasing the air pressure above the water, you are effectively increasing the vapor pressure needed for the water to boil.
-
This means the water needs to be at a higher temperature to reach this increased vapor pressure, thereby increasing the boiling point of the water.
So, the correct answer is B. By increasing the air pressure above the water.

The additional heat causes the kinetic energy of some of the liquid molecules to so they can more easily escape into the gas phase. Therefore, the temperature of the boiling water remains constant. Since some of the liquid water changes to gas, the amount of liquid water .
