To get a handle on the value of this model equation let’s go back to the ice cream scoop. The end result is obvious to our intuition, that the ice cream will eventually melt completely, because we know heat naturally flows from warm to cold. But what is not so obvious is the exact amount of time it will take that ice cream to melt all the way. Taking some additional information into account like the size of the scoop, as well as the kind of bowl or ice cream cone it’s held in, Fourier’s law gives us a good estimation for the time it takes the ice cream to melt. Which makes it very useful not just for ice cream lovers, but for anyone interested in keeping something cool in a hot environment or vice versa. Like computer chip manufacturers or airplane insulation designers.
