Phase Changes of Matter

Front

What is a gas?

Back

A state of matter that has an indefinite shape and volume, taking the shape and volume of its container.

Front

What is melting?

Back

The process where particles in a solid gain enough energy to become a liquid.

Front

What happens to the volume of a gas when its temperature increases at constant pressure?

Back

The volume increases.

Front

What is deposition?

Back

The process where gas changes directly into a solid, skipping the liquid phase, such as water vapor changing into frost.

Front

What is a solid?

Back

A state of matter where particles are packed tightly together, held by strong attractive forces, and vibrate in fixed positions.

Front

What is boiling?

Back

The process where a liquid turns into a gas when it reaches its boiling point.

Front

What is condensation?

Back

The process where a gas changes into a liquid when it loses energy.

Front

What is freezing?

Back

The process where a liquid loses energy and becomes a solid.

Front

What is sublimation?

Back

The process where a solid changes directly into a gas without becoming a liquid.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

As the temperature of a gas increases, the kinetic energy of its particles also increases.
