Cooling curve - Wikipedia
网页A cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is …
Cooling Curves — Isaac Physics
网页A cooling curve of a substance is a graph of the variation of the temperature with time as it is allowed to cool. The gradient of the cooling curve is related to the heat capacity, the thermal conductivity of the substance, and the external temperature.

网页2020年11月26日 · The arrest in cooling during solidification allows the melting point of the material to be identified on a time-temperature curve. Most systems consisting of two or more components exhibit a temperature range over …

网页2022年4月13日 · The method that is used to map the phase boundaries on a phase diagram is to measure the rate of cooling for a sample of known composition. The rate of cooling will change as the sample (or some portion of it) begins to undergo a phase change.
Heating and Cooling Curves — Overview & Examples - Expii
网页Heating and cooling curves are graphs. They plot a substance's temperature (y-axis) against heat (x-axis). For heating curves, we start with a solid and add heat energy. For cooling curves, we start with the gas phase and remove heat energy. Cooling and heating curves have five segments.

网页2023年4月12日 · A cooling curve is not exactly the reverse of the heating curve because many liquids do not freeze at the expected temperature. Instead, they form a supercooled liquid , a metastable liquid phase that exists below the normal melting point.
