What is sublimation?

Back

Sublimation is the phase change from solid to gas without passing through the liquid state. An example is dry ice (solid carbon dioxide) turning directly into carbon dioxide gas.

Front

What is deposition?

Back

Deposition is the phase change from gas to solid without passing through the liquid state. An example is frost forming on a cold surface from water vapor.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state (solid, liquid, gas) to another due to changes in temperature or pressure.

Front

What are the three main states of matter?

Back

The three main states of matter are solid, liquid, and gas.

Front

What happens to the molecules during melting?

Back

During melting, the molecules in a solid gain energy and move apart, transitioning into a liquid state.

Front

What happens to the molecules during freezing?

Back

During freezing, the molecules in a liquid lose energy and come closer together, transitioning into a solid state.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into gas at temperatures below its boiling point, usually occurring at the surface of the liquid.

Front

What is condensation?

Back

Condensation is the process where gas turns into liquid, often seen when water vapor cools and forms droplets on a surface.

Front

What is boiling?

Back

Boiling is the rapid vaporization of a liquid that occurs when it reaches its boiling point, forming bubbles throughout the liquid.

Front

What is the boiling point of water?

Back

The boiling point of water is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.
