Graphing Boyle's Law

Which of the following graphs correctly represents the relationship between the pressure and the volume of an ideal gas that is held at constant temperature?

• Graph A

• Graph B

• Graph C

• Graph D

At constant temperature, what happens to the pressure when the volume is doubled?

• It is halved.

• It is doubled.

• It remains unchanged.

• It is quadrupled.

Boyle's law states that for a given amount of gas at constant temperature, the volume and pressure of a gas vary

• directly

• proportional to the square

• inversely

• proportional to the cube

According to Boyle's law, as the pressure exerted on a gas is increased, the volume will

• increase

• remain the same

• decrease

• double in size

Jose decides to go scuba diving while on vacation in Palawan. As he swims deeper into the ocean, the pressure pushing on him increases. Based on the relationship in Boyle’s law, what would happen to the volume of Jose's lungs with this increase in pressure?

• Volume of the lungs would increase.

• Volume of the lungs would double

• Volume of the lungs would have no change

• Volume of the lungs would decrease
