## Newton's law of cooling

[′nüt·ənz ′lȯ əv ′kül·iŋ]
(thermodynamics)
The law that the rate of heat flow out of an object by both natural convection and radiation is proportional to the temperature difference between the object and its environment, and to the surface area of the object.

Heat transfer coefficient, defined as a parameter in Newton's law of cooling, characterizes the relationship of heat flux through solid/fluid interface to the temperature difference between solid surface and free stream[11].
Once the heat flux cross the boundary is solved, the corresponding HTC could be calculated by Newton's law of cooling with respect to a reference temperature, [T.
Using excerpts of a Year 12 student's report on modelling Newton's law of cooling, this paper argues that when students engage with the discourse of their mathematics classroom in a manner that promotes the communication of ideas, they employ mathematical modelling practices that reflect the cyclical approaches to modelling employed by mathematicians.
For practical applications, we can use Newton's Law of Cooling (KREITH, 2003), Equation 1.
This process is called convective mass transfer and is described by an equation similar to Newton's Law of Cooling, (CREMASCO, 2002), Equation 2.
