Suppose we forget the model for heat transfer, Q = CA ΔT; canwe drawsome information about the direction of Q from the second law?
Step 1 of 3</p>
The objective here is to evaluate if we can find out the direction of heat transfer from the second law if an equation for a heat transfer model is known.
Step 2 of 3</p>
Where C and A are constants.
Therefore, it is clear that the heat transfer depends only on temperature change.
