Boyle's Law

Which container will have a lower pressure if one is larger than the other?

• The smaller container will have lower pressure.

• Both containers will have the same pressure.

• The larger container will have lower pressure.

• The pressure cannot be determined without more information.

How does Boyle's Law apply to breathing?

• During inhalation, the volume of the lungs increases, causing pressure to decrease and air to flow in.

• During exhalation, the volume of the lungs decreases, causing pressure to increase and air to flow out.

• Boyle's Law has no effect on breathing as it only applies to gases in closed containers.

• The pressure in the lungs remains constant regardless of the volume changes during breathing.

What is the unit of pressure commonly used in Boyle's Law?

• Pascals (Pa)

• Kilopascals (kPa)

• Millimeters of mercury (mmHg)

• Atmospheres (atm)

What happens to gas pressure if the temperature is held constant and the volume is decreased?

• The pressure decreases.

• The pressure remains the same.

• The pressure increases.

• The pressure fluctuates.

True or False: Gases can be compressed.

• True

• False

• Only liquids can be compressed

• Only solids can be compressed

What happens to volume when pressure increases?

• Volume increases.

• Volume remains the same.

• Volume decreases.

• Volume fluctuates.

What happens to pressure when volume increases?

• Pressure increases.

• Pressure remains constant.

• Pressure decreases.

• Pressure fluctuates.

What is Boyle's Law?

• Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant.

• Boyle's Law states that the volume of a gas is directly proportional to its pressure when the temperature is constant.

• Boyle's Law states that the pressure of a gas increases with an increase in temperature at constant volume.

• Boyle's Law states that the volume of a gas decreases as the temperature increases at constant pressure.

If a gas has a volume of 4.0 L at 90.0 kPa and expands to a pressure of 20.0 kPa, what is its new volume?

• 10.0 L

• 15.0 L

• 18.0 L

• 22.0 L

If the volume of a gas is halved, what happens to its pressure?

• The pressure remains the same.

• The pressure doubles.

• The pressure decreases by half.

• The pressure triples.
