Now it is time for you to practice using Boyle's Law. Work out the problems in your notes.

1. A certain gas occupies a volume of 1500 cm³ at a certain pressure. When the pressure was altered to 5 atm., the volume occupied by the gas was 3000 cm³. Assuming the temperature to be constant, find the initial pressure of the gas. Interactive popup. Assistance may be required.

2. Josh is wearing scuba gear and swimming under water at a depth of 66.0 feet. He is breathing air at 3.00 atm and his lung volume is 5.0 L. His scuba gear indicates that the air supply is low so he decides to surface. In order to conserve air, he holds his breath while he surfaces.
• What will be the volume of air in his lungs when he gets to the surface if he holds his breath? Be sure to add the correct units to your answer. Interactive popup. Assistance may be required.
