Gas laws

What is the relationship between pressure and volume in a closed system?

• As one increases, the other decreases.

• Both pressure and volume increase together.

• Pressure increases while volume remains constant.

• Volume increases while pressure decreases, but not always.

What happens to gas volume when pressure is reduced?

• The volume increases.

• The volume decreases.

• The volume remains the same.

• The volume fluctuates randomly.

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

• The pressure decreases.

• The pressure increases.

• The pressure remains the same.

• The pressure fluctuates.

How does Boyle's Law apply to scuba diving?

• As a diver descends, pressure increases, causing the volume of air in their lungs to decrease.

• As a diver ascends, pressure decreases, causing the volume of air in their lungs to increase.

• Boyle's Law has no effect on scuba diving as water pressure is constant.

• The volume of water around the diver increases, affecting their buoyancy.

What is the significance of Boyle's Law in understanding gas behavior?

• It helps predict how gases will react to changes in pressure and volume.

• It explains the relationship between temperature and pressure of gases.

• It describes the behavior of gases at absolute zero temperature.

• It states that gases will always occupy a fixed volume.

What is the formula for Boyle's Law?

• P1 * V1 = P2 * V2, where P is pressure and V is volume.

• P1 + V1 = P2 + V2

• P1 / V1 = P2 / V2

• P1 * V1 = P2 + V2

What is the effect of temperature on gas pressure?

• At constant volume, increasing temperature increases pressure.

• At constant volume, increasing temperature decreases pressure.

• At constant volume, temperature has no effect on pressure.

• At constant volume, pressure remains constant regardless of temperature.

What is Boyle's Law?

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

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

• Boyle's Law states that the volume of a gas is constant regardless of pressure changes.

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

What is the definition of pressure in the context of gases?

• Pressure is the weight of gas particles in a container.

• Pressure is the force exerted by gas particles colliding with the walls of their container.

• Pressure is the temperature of gas particles in a container.

• Pressure is the volume occupied by gas particles in a container.

What happens to gas pressure when the temperature is constant and the volume decreases?

• The pressure decreases.

• The pressure remains the same.

• The pressure increases.

• The pressure fluctuates.
