6th Science Topic 2 Review

Front

What is pressure?

Back

The pressure of a gas is the force of its outward push (in Newtons) over an area (in square meters) of the walls of the container.

Front

How can you increase a substance’s thermal energy?

Back

You can increase the thermal energy of a substance by heating it.

Front

What causes solids to have a definite shape and definite volume?

Back

The particles that make up a solid are packed very closely together.

Front

How are the particles in a liquid arranged?

Back

The particles in a liquid are not fixed in place and can move around one another.

Front

Why can liquids flow from one place to another?

Back

Free moving particles allow a liquid to flow from place to place.

Front

How are the particles in a gas arranged?

Back

The particles in a gas are widely spaced and collide with one another as they move around.

Front

What is the change in state from a liquid to a solid called?

Back

Freezing

Front

What is the change of a liquid to a gas called?

Back

Vaporization

Front

When does condensation occur?

Back

Condensation occurs when particles in a gas lose enough thermal energy to change state.

Front

What did French scientist Jacques Charles discover about the relationship between the temperature and volume of a gas?

Back

French scientist Jacques Charles discovered that when the temperature of a gas at constant pressure is increased, its volume increases. He also discovered that when the temperature of a gas at constant pressure is decreased, its volume decreases.
