Entropy vs Enthalpy concept

Postby Dakota_Campbell_1C » Thu Jan 31, 2019 10:01 pm

What's the difference between enthalpy and entropy? Entropy is the measure of gain or loss of heat. Entropy is the measure of chaos, but what does that mean and does it have units?

enthalpy is the total amount of energy while entropy represents the internal disorder that results every time energy is transferred

Entropy is basically a measure of the random activity within a system, enthalpy is a measure of the overall amount of energy in the system (random or not). The more overall energy there is in a system, the more chaos there will be (higher entropy). Hope this helps!
