When Temperature of a gas increases, the Volume will ____________________

• Increase

• Decrease

• Stay the Same

Answer explanation

When the temperature of a gas increases, its particles move faster, causing the gas to expand. According to Charles's Law, the volume of a gas is directly proportional to its temperature, so the volume will increase.

According to Charles’s law, the volume of a gas is inversely proportional to its pressure at constant temperature.

• True

• False

If the initial volume is 2.5L and the temperature is 30^oC, what is the final volume if the temperature is decreased to 20^oC?

• 2.4L

• 2.4 K

• 221L

• 35L

If the initial volume is 6.3 L and the temperature is 303K, what is the final temperature if the volume is doubled?

• 152 K

• 606 K

• 0.26K
