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.

people.chem.umass.eduSuch a curve would be made by taking mixtures of varying composition, heating them to the BP, measuring that temperature, analyzing the composition of the vapor above each mixture, and plotting the results. Such a curve for cyclohexane and toluene is shown below. The lower curve represents the liquid

FUSEOLOGY - Littelfuse
www.littelfuse.comThe derating curve is deduced from the temperature rise of the component when it is crossed by a certain current: the higher is the current, the higher is the temperature reached. This is reached as a result of the Joule effect. Derating curve graphs are calculated with a safety temperature margin of 20% Main characteristics of the derating curve:

www.livingston.orgNOTE: the vapor pressure curve ends at the critical point. the temperature above which the gas cannot be liquefied no matter how much pressure is applied (the kinetic energy simply is too great for attractive forces to overcome). Any substance beyond this critical point is called a supercritical
