Solids, Liquids, Gases

Front

What are the three states of matter?

Back

Solid, Liquid, Gas.

Front

How does temperature affect the state of matter?

Back

Increasing temperature generally causes solids to become liquids (melting) and liquids to become gases (evaporation).

Front

What is the primary characteristic of solids?

Back

Molecules in solids are closely packed together and vibrate in place.

Front

What is the primary characteristic of liquids?

Back

Molecules in liquids are close together but can move past one another, allowing liquids to flow.

Front

What is the primary characteristic of gases?

Back

Molecules in gases are far apart and move freely, filling the container they are in.

Front

What happens to the speed of molecules as temperature increases?

Back

The speed of molecules increases as temperature increases.

Front

What is melting?

Back

Melting is the process of a solid turning into a liquid due to an increase in temperature.

Front

What is freezing?

Back

Freezing is the process of a liquid turning into a solid due to a decrease in temperature.

Front

What is evaporation?

Back

Evaporation is the process of a liquid turning into a gas due to an increase in temperature or decrease in pressure.

Front

What is condensation?

Back

Condensation is the process of a gas turning into a liquid due to a decrease in temperature.
