Front

What is a phase change diagram?

Back

A graphical representation that shows the states of matter (solid, liquid, gas) and the transitions between them based on temperature and pressure.

Front

What are the four main states of matter?

Back

Solid, liquid, gas, and plasma.

Front

What does the term 'melting' refer to?

Back

The phase change from solid to liquid when heat is added.

Front

What does the term 'freezing' refer to?

Back

The phase change from liquid to solid when heat is removed.

Front

What does the term 'boiling' refer to?

Back

The phase change from liquid to gas that occurs when a liquid reaches its boiling point.

Front

What does the term 'condensation' refer to?

Back

The phase change from gas to liquid when heat is removed.

Front

What is sublimation?

Back

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

Front

What is deposition?

Back

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

Front

What is the significance of point 'g' in a phase change diagram?

Back

It typically represents a solid state of matter.

Front

What is the significance of point 'b' in a phase change diagram?

Back

It typically represents a liquid state of matter.
