Mario uses a hot plate to heat a beaker of 50mL of water. He used a thermometer to measure the temperature of the water. The water in the
beaker began to boil when it reached the temperature of 100 degrees Celsius. If Mario completes the same experiment with 25 mL of water, what would happen to the boiling point? *

The boiling point decreases as the volume decreases.

Explanation:

The Temperature - Volume law otherwise called as Charles law is applied, which says that the volume of the given gas at constant pressure is directly proportional to the temperature measured in Kelvin. As the volume increases, the temperature also increases, if the volume decreases, then the temperature also decreases.

As per the Charles law, here the volume is decreased from 50 ml to 25 ml so the boiling point also decreases.
