Gas Pressure

Front

What happens to the energy of a substance when it changes from liquid to gas?

Back

The energy has to INCREASE.

Front

What happens to the particles of matter when the temperature increases?

Back

The particles speed up and move farther apart.

Front

What causes gas pressure?

Back

Gas pressure is caused by gas molecules colliding with each other and the walls of the container.

Front

Which container will have a lower pressure if one is left and the other is right?

Back

The left container will have a lower pressure.

Front

How do gas molecules move?

Back

Gas molecules move constantly and randomly.

Front

Define gas pressure.

Back

Gas pressure is the force exerted by gas molecules colliding with surfaces.

Front

What is the relationship between temperature and gas particle movement?

Back

As temperature increases, gas particles move faster.

Front

What happens to gas pressure if the volume of the container decreases?

Back

Gas pressure increases when the volume of the container decreases.

Front

What is the effect of adding more gas molecules to a container at constant temperature?

Back

Adding more gas molecules increases the pressure.

Front

Explain the concept of kinetic energy in relation to gas molecules.

Back

Kinetic energy is the energy of motion; gas molecules have high kinetic energy and move rapidly.
