Gas Laws and The Kinetic Molecular Theory

A sample of neon gas is trapped in a 2.0 L box with a set volume. If the temperature of the gas is doubled

• pressure decreases

• pressure is doubled

• the pressure stays the same

• pressure is halved

When more gas is added to a container with a set volume, the number of collisions increases which increases the (a)   .

The pressure of a gas is 4.0 mL at 1.0 atm. What is the pressure of the gas at 2.0 mL?

• 1.0 atm

• 2.0 atm

• 1.5 atm

• 0.5 atm

The controlled variable for the combined gas law is

• number of gas particles

• temperature

• pressure

• volume

The measure of the average kinetic energy of a gas is

• volume

• pressure

• collisions

• temperature

The temperature of a gas is 23 degrees Celsius. At this temperature, the volume is 24.0 mL. Determine the volume of the gas when the temperature is 35 degrees Celsius.

• 0.027 mL

• 0.037 mL

• 36 mL

• 27 mL

According to the Kinetic Molecular Theory

• gas particles are attracted to one another

• gas particles move in curved paths

• gas particles lose energy during collisions

• gas particles travel in straight lines until collisions occur

Determine the temperature of a gas at 0.87 atm and 1.2 mL if the same gas has a volume of 4.5 mL at 0.92 atm at 23.5 degrees Celsius.

• 0.013 deg C

• 0.014 K

• 5.9 deg C

• 75 K

The relationship between pressure and temperature at constant volume and number of particles is

• directly proportional

• inversely proportional

• variable

• defined

Which is true regarding the gas on the left versus the gas on the right?

• The gas on the left exerts a higher pressure.

• The gas on the left exerts a lower pressure

• The gas on the left exerts the same pressure as the gas on the right.

• The gas on the left makes more collisions than the gas on the right.
