Unit 3A Review-IMF and Ideal Gas

Determine the number of moles in a container of gas at 1 atm with a volume of 99.2 L and a temperature of 100K.

• 12 mol

• 120 mol

• 10 mol

• 100 mol

If the pressure exerted by a gas at 298 K in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

• 6.85 mol

• 0.007 mol

• 6.9 mol

• 0.0069 mol

When the temperature of matter increases the particles...

• speed up and move closer
• speed up and move farther apart
• slow down and move closer together
• slow down and move farther apart

How do gas molecules move? 

• in an orderly fashion 
• constantly and randomly
• in straight line paths
• in a circular motion

When Pressure increases then the Volume must...

• Increase
• decrease

When Volume increases then Pressure must...

• Increase
• Decrease

What type of relationship to pressure and volume have?

• direct
• inverse
• no relationship
• I don't know

Which container will have a lower pressure?

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

Gases have...

• A definite shape and volume
• A definite shape but no definite volume
• No definite shape but a definite volume
• No definite shape or volume

What is the variable for this number 22.4 L

• P
• T
• n
• V
