What is the cooling curve?
The cooling curve is a type of graph used in chemistry, physics, engineering and other disciplines that map the progress of cooling substances. One graph axis, usually X -axis, maps time while the temperature is represented on the other axis. As such, the cooling curve generally decreases down from left to right when the temperature decreases over time. It is important to note that such a curve does not always proceed during the graph at a uniform speed, because the cooling curves are often used to display changes in the physical phase, such as change from water to ice. The temperature is reduced at a uniform speed when the water cools to the freezing point, but the curve is equalized at the freezing point when liquid water freezes to a solid ice.
can affect the progression of the cooling curves by many different factors. Two of the most important factors are the initial temperature of the cooling substance, often called the "temperature of pouring" and the temperature to which the substance has poured. Specific features of the cooling substance are the main determinants of the progression of the cooling curve. Another FaKTORY, such as pressure and coolant volume, can also drastically affect the curve.
It is not uncommon for the cooling curve to display a phase change, such as the gas to the liquid or from the liquid to the solid. Transformation from water to ice is one of the most famous and widespread examples of phase change. When the water is added to the environment at a relatively high temperature at a temperature below freezing, it is generally cooled at a uniform speed until it reaches the temperatures of frost. At this point, the temperature ceases to decrease until all the water solidifies on the ice. The cooling water loses energy in the form of heat and therefore causes the temperature to reduce, but the same energy loss is also necessary for transition from the liquid to the solid, only without the corresponding temperature change.
Scientists and students can use different methods to produce cooling curves. The simplest method involves adding a substance to a temperature -controlled environment and a pomThe thermometer's desire records the temperature of the substance at regular intervals. However, this method is sensitive to a human error. Other methods are relying on electronic temperature sensors and computer recording software instead. Such devices and software can be used to create a precise cooling curve in real time while reducing the chance that the experimental error causes the cooling curve to cause unnecessary.
