Review 3 change of states/states of matter

Front

What is a solid?

Back

A state of matter where molecules are closely packed together, maintaining a definite shape and volume.

Front

What is a liquid?

Back

A state of matter that has a definite volume but no definite shape, taking the shape of its container.

Front

What is a gas?

Back

A state of matter with no definite shape and no definite volume, where molecules are far apart and move freely.

Front

What is deposition?

Back

The change of state from a gas directly to a solid, skipping the liquid phase.

Front

What is sublimation?

Back

The change of state from a solid directly to a gas, skipping the liquid phase.

Front

What is condensation?

Back

The process where gas turns into a liquid, often seen as water droplets forming on a cold surface.

Front

What is evaporation?

Back

The process where liquid turns into gas, usually occurring at the surface of the liquid.

Front

What are the three main states of matter?

Back

Solid, liquid, and gas.

Front

What happens to molecules in a solid when heated?

Back

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

Front

What happens to molecules in a gas when cooled?

Back

They lose energy, move closer together, and may condense into a liquid.
