chemistry-igcse1.weebly.comSo if you record the temperature change during heating a solid, the temperature will first rise, then it will remain constant for a while (this is the melting point) and then it will rise again. The following figure is a heating curve of a solid. At point ‘A’ the state is …

Heating and Cooling Curves (The Basics)
www.rcboe.orgtime is called a heating curve. Let's look at the heating curve for water. Heating Curves Notice that, in general, the temperature goes up the longer the heating continues. However, there are two horizontal flat parts (segments BC and DE) to the graph. These happen when there is a change of state. The plateaus are also called phase changes.
