WebJun 22, 2016 · There is a theorem which states that any solution of the heat equation in a region of ( x, t) must have its extrema (minima and maxima) on the boundary of that region. In this case, the region is ( x, t) ∈ [ 0, 1] × [ 0, ∞). On ( x = 0, t > 0) the solution is fixed at 2. On ( x = 1, t > 0) the solution is fixed at 3. WebSep 7, 2024 · 1 Answer. d T d t = − k ( T − T a) …. ( i) (Here the use of minus sign is due to the fact that the temperature is decreasing.) In this ODE, t is the time, T ( t) is the temperature at time t and T a is the temperature of the object's environment. In your case T a is the temperature of the freezer i.e T a = − 15.
