Phase Change Diagram Quiz

Use the phase change diagram above to match the portion of the diagram to the appropriate description.

• C to D

• heat energy is still being added, temperature is CONSTANT, the solid is melting

• E & beyond

• heat energy continues to be added, temperature continues to increase, the substance is in the gas phase

• B to C

• heat energy is being added, temperature is increasing, particles are beginning to move more rapidly

• A to B

• heat energy is being added, temperature is CONSTANT, the substance is starting to evaporate (vaporization)

• D to E

• heat energy is being added, temperature is increasing, the substance is in the liquid phase and the particles are moving increasingly more rapidly
