Liquid, Solid, and Gas

Front

What is matter?

Back

Matter is anything that has mass and takes up space. It can exist in three states: solid, liquid, and gas.

Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas.

Front

What is a solid?

Back

A solid is a state of matter that has a definite shape and volume. The particles in a solid are closely packed together.

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 in a liquid are close together but can move around.

Front

What is a gas?

Back

A gas is a state of matter that has no definite shape or volume. The particles in a gas are far apart and move freely.

Front

How do particles behave in a solid?

Back

In a solid, particles vibrate in place but do not move around freely.

Front

How do particles behave in a liquid?

Back

In a liquid, particles are close together but can slide past one another, allowing liquids to flow.

Front

How do particles behave in a gas?

Back

In a gas, particles move quickly and are far apart, allowing gases to fill the entire space available.

Front

What happens to a solid when it is heated?

Back

When a solid is heated, its particles gain energy and may begin to vibrate more vigorously, potentially changing into a liquid.

Front

What happens to a liquid when it is heated?

Back

When a liquid is heated, its particles gain energy and may move faster, eventually turning into a gas.
