Gas Pressure and Temperature Concepts

What causes gas pressure in sealed containers?

To increase the gas pressure in a container you could…

• Increase the # of gas particles

• Decrease the # of gas particles

Applying force to the piston pictured to the right results in the compression of the gas particles at a constant tempurature causing an increase in gas pressure.

Which one of the following best describes the change in gas particles after conversion?

• The average kinetic energy of the gas particles increases.

• The average kinetic energy of the gas particles decreases.

• The gas particles hit the container walls more often with increased frequency

• The gas particles hit the container walls harder with increased energy and force

If the volume of a gas sample is doubled, the pressure of the gas will be…

• Halved

• The same

• Doubled

• Quadrupled

If the absolute tempurature of a gas sample is doubled, the pressure of the gas will be…

• Half as much

• The same

• 2 times as much

• 4 times as much

If the absolute tempurature of a gas sample is doubled while the volume is halved, the pressure of the gas will…

• Half as much

• The same

• 2 times as much

• 4 times as much

Which of the following changes will cause the greatest decrease in the volume of a gas in a flexible container?

• Removing particles of gas while increasing temperature

• Adding particles of gas while decreasing temperature

• Removing particles of gas while decreasing temperature

• Adding particles of gas while increasing temperature
