Changes in Matter

Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What happens to the particles in a solid when heat is added?

Back

The particles gain energy and vibrate more, leading to melting.

Front

Define melting in terms of state changes.

Back

Melting is the process where a solid turns into a liquid when heat is added.

Front

What is evaporation?

Back

Evaporation is the process where a liquid turns into a gas when heat is applied.

Front

What is condensation?

Back

Condensation is the process where a gas turns into a liquid when it cools down.

Front

What is the difference between boiling and evaporation?

Back

Boiling occurs at a specific temperature throughout the liquid, while evaporation can occur at any temperature.

Front

What is sublimation?

Back

Sublimation is the process where a solid turns directly into a gas without becoming a liquid.

Front

What is the term for a gas turning into a solid?

Back

Deposition.

Front

How does temperature affect the state of matter?

Back

Increasing temperature generally increases energy, causing matter to change from solid to liquid to gas.

Front

What is the role of pressure in changing states of matter?

Back

Increasing pressure can force gas into a liquid state, while decreasing pressure can allow a liquid to evaporate more easily.
