Concept Map

Organise the vocabulary, quantities and relationships into a connected model.

This extension applies that lens specifically to Heating and Cooling Curves.

If you heat a solid steadily and plot temperature against time, you get a heating curve with flat steps:

  • The temperature rises while the substance is in one state (particles speed up).
  • The temperature stays flat during a change of state, even though heating continues. The energy is going into breaking the forces between particles, not raising the temperature.

The first flat step is at the melting point; the second is at the boiling point. A cooling curve is the mirror image: flat steps where the substance freezes and condenses.
