Lesson 1.8 Review Gas Properties

How is the volume of a contained gas related to its density?

• As the volume of a contained gas increases, the density will increase.

• As the volume of a contained gas decreases, the density will decrease.

• As the volume of a contained gas decreases, the denisty will remain constant.

• As the volume of a contained gas decreases, density will increase.

Which set of conditions would cause the volume of a contained gas to increase?

• Temperature of the gas increases.

• Temperature of the gas decreases.

• Pressure of the gas decreases.

• Pressure of the gas remains constant.

• I don't know.

Joey uses a bike pump to put more air in his bike tire. By adding more air, the the additional gas will

• decrease the pressure of the gas.

• have no affect on the pressure of the gas.

• decrease the density of the air molecules in the tire.

• increase the pressure of the gas.

• I don’t know

As volume of the gas in this container increases, pressure will

• decrease.

• remain the same.

• increase.

• I don’t know

Each cylinder contains the same amount of gas molecules, which cylinder is under greater pressure?

• Cylinder 1

• Cylinder 2

• Cylinder 3

• I don't know

Pressure increases with ocean depth. When a scuba diver dives to a depth of 30 meters, the pressure of the surrounding water will (pick the two correct answers)

• decrease the volume of the air in his lungs.

• increase the volume of air in his lungs.

• decrease the density of the air molecules in his lungs, which will make him more buoyant.

• increase the density of the air molecules in his lungs, which will make him less buoyant.

• I don't know

The density of the gas, in g/L, is

• greatest in container A

• greatest in container B

• greatest in container C

• the same in all three containers

What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase
• Decrease
• Nothing
• Explosion!

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

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
