Properties of Gases & KMT

Which container will have lower pressure?

• left

• right

• they both have the same pressure

• they both don't have any pressure

What could you do to make the stopper pop out of the flask?

• Decrease pressure

• Decrease temperature

• Increase volume

• Increase temperature

If you increase the pressure of a constant volume of gas, what will happen to the temperature?

• Increase

• Decrease

• Stay the same

• It will Blow Up

How are pressure and volume related?

• Directly

• Indirectly

• They aren't related

• Exponentially

What is the basis of the kinetic molecular theory?

• Molecules are in constant motion.

• Molecules only stop sometimes.

• Approximately half the molecules are stationary.

• It is impossible to tell if a molecule is moving or not.

A gas that conforms exactly to the four assumptions of the KMT is called a(n)...

• Model gas

• Ideal gas

• Perfect gas

• Real gas

Any gas that does NOT conform to the four assumptions of the KMT is called a(n)...

• Complex gas

• Imperfect gas

• Real gas

• Specific gas

True or false?  All gases expand to fill their container.

• True
• False

When gas particles escapes through tiny holes, often the size of molecules or atoms this is known as

• Effusion

• Diffusion

• Osmosis

• Gas escape

When a substance mixes due to random moving particles, this is known as

• Effusion

• Diffusion

• Osmosis

• Kinetic-molecular movement
