The equation Q = ΔU represents the first law of thermodynamics, stating that heat transfer (Q) is equal to the change in internal energy (ΔU) of a system. It accounts for energy conservation in thermodynamic processes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
