Answer : The final volume of balloon will be, 3.35 L
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,
= initial pressure = 789 mmHg
= final pressure = 632 mmHg
= initial volume = 2.68 L
= final volume = ?
Now put all the given values in the above equation, we get:


Therefore, the final volume of balloon will be, 3.35 L
Water always boils at 212 degrees F, or 100 degrees C. Because the boiling point is not dependent on the size of the sample of water, it would be an intensive property.
