Phase Changes - Phase Diagrams

Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What is a phase diagram?

Back

A graphical representation showing the states of matter at different temperatures and pressures.

Front

What is the triple point?

Back

The condition under which all three phases (solid, liquid, gas) coexist in equilibrium.

Front

What is the critical point?

Back

The temperature and pressure at which a substance can no longer exist as a liquid or gas.

Front

What happens at the normal melting point?

Back

A solid turns into a liquid at a specific temperature under standard atmospheric pressure.

Front

What is sublimation?

Back

The process where a solid turns directly into a gas without passing through the liquid phase.

Front

What is deposition?

Back

The process where a gas turns directly into a solid without passing through the liquid phase.

Front

What is the significance of the equilibrium point in a phase diagram?

Back

It indicates the conditions under which two phases can coexist in equilibrium.

Front

What is a supercritical fluid?

Back

A state of matter that occurs when a substance is above its critical temperature and pressure, exhibiting properties of both liquid and gas.

Front

What is vaporization?

Back

The process where a liquid turns into a gas.
