States of Matter

Front

What is the main factor that causes a change in the state of matter?

Back

The main factor that causes a change in the state of matter is the increase or decrease in energy (heat).

Front

Do particles in solids move around a lot?

Back

No, particles in solids do not move around a lot; they are closely packed and vibrate in place.

Front

What is the shape and volume of a liquid?

Back

Liquids have a fixed volume but do not have a fixed shape; they take the shape of their container.

Front

Which state of matter has the least kinetic energy?

Back

Solids have the least kinetic energy compared to liquids and gases.

Front

What is the phase change from liquid to gas called?

Back

The phase change from liquid to gas is called vaporization.

Front

What happens to the energy of particles when a substance freezes?

Back

When a substance freezes, the energy of the particles decreases, causing them to move closer together.

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid.

Front

What is sublimation?

Back

Sublimation is the phase change from solid to gas without passing through the liquid state.

Front

How do gas particles behave compared to solid and liquid particles?

Back

Gas particles move freely and are far apart, allowing them to fill the entire volume of their container.

Front

What is the relationship between temperature and the kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles also increases.
