Front

What is a phase diagram?

Back

A graphical representation showing the phases of a substance at different temperatures and pressures.

Front

What does the line segment A-B represent in a phase diagram?

Back

The solid state of the substance.

Front

What does the line segment B-C represent in a phase diagram?

Back

The phase change from solid to liquid, known as melting.

Front

What does the line segment C-D represent in a phase diagram?

Back

The liquid state of the substance.

Front

What does the line segment D-E represent in a phase diagram?

Back

The phase change from liquid to gas, known as boiling.

Front

What is the significance of the flat regions in a phase diagram?

Back

They indicate phase changes where temperature remains constant while the substance changes state.

Front

What is the triple point in a phase diagram?

Back

The unique set of conditions where all three phases (solid, liquid, gas) coexist in equilibrium.
