delta S

If delta S equals delta H/ temperature, does that mean the more you decrease temperature the higher delta S is?

Yes, the change in entropy is greater at lower temperatures than higher temperatures.

But I remember hearing that when temperature is zero, than delta S is also 0. Or is that wrong.

That is right because the Third Law of Thermodynamics, states that materials have zero entropy at 0K.

If you think about it algebraically it would make sense. Dividing by a smaller number vs dividing by a larger one will give you a larger value. So temperature which is the variable that will be in the denominator will determine the size of your value. Lower temp = greater change in entropy.
