Gases Test Review

You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L
• 20 L
• It would stay at 10L
• 1 L

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

At standard temperature and pressure, I have 48L of hydrogen gas. How many moles of gas do I have?

• 0.5
• 1
• 2
• 4

A sample of an ideal gas containing 0.954 mol is collected at 742 torr pressure and 31°C. Calculate the volume. 

• 22.4 L
• 24.4 L
• 0.224 L
• 0.222 L

Which is NOT an assumption made by the kinetic molecular theory of gases?

• Gas particles are small and take up little volume
• Particles travel in constant, random, straight-line motion until colliding
• When particles collide, their total kinetic energy is decreased
• Particles do not attract or repel each other

The kinetic molecular theory describes particles in a __________.

• real gas
• ideal gas
• room temperature
• at normal pressure

The same amount of air is stored in identical containers. Sample A is kept at a temperature of 200K while Sample B is kept at 400K. What is true about the samples?

• The pressure in A is half of the pressure in B

• The pressure in A is double the pressure in B

• The pressure in A and B are the same

• Not enough information...

Gas particles colliding with each other and the walls of the container they're kept in is called

• Pressure

• Temperature

• Volume

• Red Rover 2.0

The relationship between volume and temperature is

• direct

• inverse

• built on trust

• going through rough times after what temperature did last weekend

The relationship between volume and pressure is

• direct

• inverse

• mostly done on snapchat

• just starting after watching Black Panther together
