States of Matter Review

Front

What is a solid?

Back

A solid is a state of matter that has a fixed shape and volume. The particles are closely packed together and do not move around much, only vibrating in place.

Front

What is a liquid?

Back

A liquid is a state of matter that has a definite volume but takes the shape of its container. The particles are close together but can move around freely.

Front

What is a gas?

Back

A gas is a state of matter that has no fixed shape or volume. The particles are far apart and move freely, filling the entire space available.

Front

Can water exist in different states of matter?

Back

Yes, water can exist as a solid (ice), a liquid (water), and a gas (water vapor).

Front

What happens to the particles in a solid when heated?

Back

When a solid is heated, its particles gain energy and begin to vibrate more vigorously, which can eventually lead to melting.

Front

What happens to the particles in a liquid when heated?

Back

When a liquid is heated, its particles gain energy and move faster, which can lead to evaporation.

Front

What is melting?

Back

Melting is the process by which a solid turns into a liquid when it is heated.

Front

What is freezing?

Back

Freezing is the process by which a liquid turns into a solid when it is cooled.

Front

What is evaporation?

Back

Evaporation is the process by which a liquid turns into a gas when it is heated.

Front

What is condensation?

Back

Condensation is the process by which a gas turns into a liquid when it is cooled.
