Front

What is Brownian motion?

Back

The random and constant motion of atoms or particles suspended in a fluid (liquid or gas) due to collisions with fast-moving molecules.

Front

What is sublimation?

Back

The process in which a solid changes directly into a gas without first becoming a liquid.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

What is melting?

Back

The process in which a solid turns into a liquid when heated.

Front

What is condensation?

Back

The process in which a gas turns into a liquid when cooled.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is evaporation?

Back

The process by which liquid turns into vapor, usually at temperatures below boiling.

Front

What is freezing?

Back

The process in which a liquid turns into a solid when cooled.

Front

What is deposition?

Back
