Molecules In Motion

Front

What is a solid?

Back

A solid is a state of matter where particles are tightly packed together and have a fixed shape and volume. Example: rock.

Front

What is a liquid?

Back

A liquid is a state of matter where particles are close together but can move and slide around each other. Example: water.

Front

What is a gas?

Back

A gas is a state of matter where particles are far apart and move freely. Example: air.

Front

What are the three states of matter?

Back

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

Front

What is convection?

Back

Convection is the process by which heat travels through liquids and gases due to the movement of the particles.

Front

What happens to particles in a solid?

Back

Particles in a solid are tightly packed together and are locked in place.

Front

What happens to particles in a liquid?

Back

Particles in a liquid are close together but can move and slide past each other.

Front

What happens to particles in a gas?

Back

Particles in a gas are far apart and move freely, filling the space available.

Front

How does temperature affect the state of matter?

Back

Increasing temperature can change a solid to a liquid (melting) and a liquid to a gas (evaporation).

Front

What is an example of a gas?

Back

An example of a gas is air.
