Kinetic Particle Model

Which statement about the molecules in the gas carbon dioxide is correct?

• The molecules are close together.

• The molecules are diatomic.

• The molecules move randomly.

• The molecules all move with the same speed.

An inflated balloon is placed in a refrigerator. Which statement describes the movement of the gas particles in the balloon?

• The particles move more slowly and become closer together.
• The particles move more slowly and become further apart.
• The particles move faster and become closer together.
• The particles move faster and become further apart. 

The more energy particles have...

• the faster they move.

• the farther apart they tend to be.

• the hotter they are.

• All of the above

If the temperature of a gas increase, the pressure...

• Decreases
• Increases
• Does not change

Which container will have a lower pressure?

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

When Pressure increases then the Volume must...

• Increase
• decrease

• c. As the temperature increases, volume increases at constant pressure.

• d. As the pressure increases, volume increases at constant temperature.

2. What do you expect to happen to the volume of a gas if its pressure is

doubled and its temperature is reduced to half?

• a. its volume is increased

• b. its volume is doubled

• c. its volume remains unchanged
