What are cooling curves used for?
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. Below is an example of a cooling curve used in castings.Click to see full…

Thereof, how are cooling curves used in industry?1.3 Cooling Curves. Cooling curves are used for illustration and evaluation of the quenching characteristics of a quenchant. A cooling curve is obtained using a thermocouple inserted in a workpiece or test probe. The part is heated and then quenched in the cooling medium. what affects the rate of cooling? If the liquid is water, then for your purposes the things controlling the rate of cooling would be as follows: 1) the thermal conductivity of the material from which the water container is made. 2) the thickness of the container walls; thinner means faster heat loss. 3) the ambient temperature of your laboratory. In this regard, what is the difference between a heating curve and a cooling curve? Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.Is a cooling curve endothermic or exothermic?On any heating curve, energy is added and therefore it is always endothermic. True or False: On any cooling curve, energy is released and therefore it is always exothermic.
