1. A balloon contains 14.0 L of air at a pressure of 760 torr. What will the volume of the air be when the balloon is taken to a depth of 10 ft in a swimming pool where the pressure is 981 torr? The temperature of the air does not change.



1. My grandmother was hospitalized at the Community Hospital due to difficulty in breathing. The nurse supported her breathing with the aid of oxygen gas. The nurse noted that the tank of oxygen gas has a volume of 14.0L and a pressure of 1 atm. Find the volume of the oxygen when its pressure is changed to 1.2 atm while the temperature is held constant.

Given: V1=14.0 L, P1= 1.0 atm, P2= 1.2 atm
