Witryna24 mar 2015 · 1. Newton's law serves equally for cooling or warming situations: d T d t = k ( T e − T) The general solution is T ( t) = T e + ( T 0 − T e) e − k t; where T 0 = T ( 0) is the initial reading we are going to find. In this case T e = 390 ∘ F is the oven temperature; so we can write. T ( t) = 390 + ( T 0 − 390) e − k t. WitrynaSuppose a very hot object is placed in a cooler room.
