Therefore, from equation three, we see that if this delta s universe is to be positive, then what that means is this quantity. So the delta S of the system must be greater than this quantity, this term here, because if this is a greater number than this, then the difference will be a positive value. So let's call this inequality inequality six. Now, if we take inequality six and we multiply both sides by T, so we simply bring T to the left side, then we get the following equation. What this equation tells us is for our process to actually increase the entropy of the universe, this inequality must be true. So T multiplied by delta S of the system should be greater than the delta H of the system.
