I have studied about heat transfer through conduction only in steady state but I wondered about this problem that I created.

Suppose you have a box that is insulated from all sides but Suppose a constant heat flow from that wall. Inside that box you have M kg of water at the same temperature initially as the wall.

lets say the temp at the inner wall is T2 and from outside T1. T1>T2. Calculate the time it takes for the water to reach a certain temp.

Or you can change the problem to having T1 to be constant at all times.

In both cases, I needed the distribution of temperatures along the thickness of the wall. In basic terms, How do you solve this kind of problems?

Excuse me if I am saying non-sense stuff. We are only required to solve steady state questions but I just wonder.
