Phase Change Diagram

Front

What is the triple point?

Back

The condition at which the solid, liquid, and gas phases of a substance coexist in equilibrium.

Front

What is a chemical change?

Back

A process where substances transform into different substances with different properties, often indicated by the formation of a precipitate.

Front

What is sublimation?

Back

The phase change from solid to gas without passing through the liquid state.

Front

What is condensation?

Back

The phase change from gas to liquid, often occurring when gas cools down.

Front

What happens to temperature during a phase change?

Back

The temperature remains constant during a phase change, even though heat is added or removed.

Front

What is melting?

Back

The phase change from solid to liquid, occurring when a solid absorbs heat.

Front

What is freezing?

Back

The phase change from liquid to solid, occurring when a liquid loses heat.

Front

What is evaporation?

Back

The phase change from liquid to gas, occurring at the surface of a liquid as it absorbs heat.

Front

What is boiling?

Back

The rapid phase change from liquid to gas that occurs throughout the liquid at a specific temperature.

Front

What is deposition?

Back

The phase change from gas to solid without passing through the liquid state.
