Description: May 21, 2021 · Heating curves relate temperature changes to phase transitions. A superheated liquid , a liquid at a temperature and pressure at which it should be a gas, is not stable. A cooling curve is not exactly the reverse of the heating curve because many liquids do not freeze at the expected temperature.

Description: Introduction. In this section, we continue analyzing phase diagrams (plots of pressure vs. temperature) and correlate them to the heating curves (plots of temperature vs. energy) that you learned about earlier in the semester. We will also continue to use the phase diagram to understand the conditions needed for phase transitions.
