Front

What is a solid?

Back

A state of matter with a definite shape and volume, where particles are closely packed together and vibrate in place.

Front

What is a liquid?

Back

A state of matter that has a definite volume but takes the shape of its container, with particles that are close together but can move past one another.

Front

What is a gas?

Back

A state of matter that has no definite shape or volume, with particles that are far apart and move freely.

Front

What state of matter has the greatest attraction between particles?

Back

Solid.

Front

What state of matter has the weakest intermolecular attraction between particles?

Back

Gas.

Front

What happens to the particles in a solid when heated?

Back

They gain energy, vibrate more, and may eventually change to a liquid.

Front

What happens to the particles in a liquid when heated?

Back

They gain energy, move faster, and may eventually change to a gas.

Front

What is the particle theory of matter?

Back

The theory that all matter is made up of tiny particles that are in constant motion.

Front

How do particles behave in a gas?

Back

They move freely and quickly, filling the entire space available.
