WebNewton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings). The time a substance takes to cool off depends on the temperature difference between the substance and the surroundings.

Web22 Nov 2024 · What is the rate of cooling? In mathematic terms, the cooling rate is equal to the temperature difference between the two objects, multiplied by a material constant. The cooling rate has units of degrees/unit-time, thus the constant has units of 1/unit-time. WebCooling even faster—for instance, by quenching the steel at about 1,000° C per minute—results in a complete depression of carbide formation and forces the undercooled ferrite to hold a large amount of carbon atoms in solution for which it actually has no room. This generates a new microstructure, martensite.
