Boyle’s law

State Boyle’s law

• boiling is controlled by volume

• volume is inversely proportional with pressure

• gas particles are far apart

• pressure of gas is always high

The volume of ammonia is changed 6.1 L. The change occurred when the pressure was changed from 520 mmHg to 790 mmHg. What was the original volume?

• 4.0 mmHg

• 4.8 mmHg

• 11.2 L

• 2.3 mmHg

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

• It is doubled

• It is halved

• It remains the same

• It disappears

To use Boyle's Law, which of the following needs to remain constant?

• Temperature and number of moles of a gas

• Volume and temperature

• Pressure and volume

• Pressure and number of moles of a gas

Decreasing the volume of a closed container of gas will cause the pressure to _________.

• Increase

• Decrease
