8th 2 Unit Quarter exam

The faster the gas particles move...

• the lower the force with which they collide with the walls of their container.

• the greater the force with which they collide with the walls of their container.

• has no impact on the force with which they collide with the walls of their container.

When the temperature of a gas at constant volume is increased...

• the pressure of the gas decreases.

• the pressure remains the same.

• the pressure of the gas increases.

• the pressure can either increase or decrease.

What causes a truck's tires to burst on long road trips?

• Hot temperatures increase the pressure inside the tire.

• Lower temperatures decrease the volume.

• Lower pressure is caused by lower temperatures.

Predict: What do you think will happen when you dunk a balloon in ice water?

• The balloon will remain the same size because temperature change does not affect the volume.

• The ballon will become smaller because lower temperatures will cause the volume to decrease.

• The balloon will become larger because lower temperatures will cause the volume to increase.

When the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at constant pressure is decreased, it's volume decreases.

• Boyle's Law

• Charle's Law

• Law of Temperature and Volume

When a gas absorbs heat...

• The particles move faster.

• The particles move at the same rate of speed.

• The particles move slower.

When a graph of two variables is a straight line passing through the origin (0,0), the variables are said to be...

• independent

• unrelated

• directly proportional

• inversely proportional

Charle's Law shows that the volume of a gas is....

• inversely proportional to its temperature.

• directly proportional to its temperature.

• unrelated to its temperature

• independently related to its temperature.

When the pressure of a gas at a constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.

• Boyle's Law

• Charle's Law

• Law of Indirectly Proportional pressure and volume

As you push down the plunger of air pump, the pressure inside the cylinder of the pump...

• decreases

• increases

• remains the same
