Gas Laws

Which container will have a lower pressure?

• left
• right
• they both have the same pressure
• I don't know

The faster the gas particles move...

• the lower the force with which they collide with the walls of their container.

• the greater the force with which they collide with the walls of their container.

• has no impact on the force with which they collide with the walls of their container.

When the temperature of a gas at constant volume is increased...

• the pressure of the gas decreases.

• the pressure remains the same.

• the pressure of the gas increases.

• the pressure can either increase or decrease.

When a graph of two variables is a straight line passing through the origin (0,0), the variables are said to be...

• independent

• unrelated

• directly proportional

• inversely proportional

Charle's Law shows that the volume of a gas is....

• inversely proportional to its temperature.

• directly proportional to its temperature.

• unrelated to its temperature

• independently related to its temperature.

Determine the Celsius temperature of 2.49 moles of gas contained in a 1.00-L vessel at a pressure of 143 kPa. 

• -266 degrees C
• -622 degrees C
• 622 degrees C 
• 266 degrees C

Determine the number of moles in a container of gas at STP with a volume of 99.2 L. 

• 2222.08 moles
• 4.43 moles
• 22.4 moles 
• 76.8 moles

If the pressure exerted by a gas at 25 degrees C in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

• .002766 mol

• .0069 mol
• 2.766 mol
• 9.887 mol

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 

Calculate the volume that a 0.323-mol sample of a gas will occupy at 265 K and a pressure of 0.900 atm.

• 7.18 L 
• 7.81 L
• 4.63 L
• 4.36 L
