Gas Pressure and Volume Quiz

What causes the pressure of a gas?

• The collisions of particles with the walls of the container

• The colour of the gas

• The temperature of the gas

• The weight of the gas

What happens to the pressure of a gas if the volume of the container is increased while keeping the temperature constant?

• The pressure increases

• The pressure decreases

• The pressure remains the same

• The pressure fluctuates

If the volume of a gas is doubled, what happens to the pressure, assuming temperature is constant?

• The pressure is halved

• The pressure remains the same

• The pressure is quadrupled

• The pressure is doubled

What is the relationship between the pressure and volume of a gas at constant temperature?

• Inversely proportional

• Directly proportional

• Exponentially proportional

• Unrelated
