I end up with less enthalpy than I started with. But, entropy increases. Disorder increases the number of states that my system can take on increases. Well, this makes Free Power lot of sense. This makes Free Power lot of sense that this is going to happen spontaneously, regardless of what the temperature is. I have these two molecules. They are about to bump into each other. And, when they get close to each other, their electrons may be, say hey, “Wait, there’s Free Power better configuration here “where we can go into lower energy states, “where we can release energy “and in doing so, “these different constituents can part ways. ” And so, you actually have more constituents. They’ve parted ways. You’ve had energy released. Entropy increases. And, makes Free Power lot of sense that this is Free Power natural thing that would actually occur. This over here, this is spontaneous. Delta G is, not just Delta, Delta G is less than zero. So, this one over here, I’m gonna make all the spontaneous ones, I’m gonna square them off in this green color. Now, what about this one down here? This one down here, Delta H is greater than zero. So, your enthalpy for this reaction needs to increase, and your entropy is going to decrease. So, that’s, you know, you can imagine these two atoms, or maybe these molecules that get close to each other, but their electrons say, “Hey, no, no. ” In order for us to bond, we would have to get to Free Power higher energy state. We would require some energy , and the disorder is going to go down. This isn’t going to happen. And so, of course, and this is Free Power combination, if Delta H is greater than zero, and if this is less than zero, than this entire term is gonna be positive. And so, Delta G is going to be greater than zero. So, here, Delta G is going to be greater than zero. And, hopefully, it makes some intuitive sense that this is not going to be spontaneous. So, this one, this one does not happen. Now, over here, we have some permutations of Delta H’s and Delta S’s, and whether they’re spontaneous depends on the temperature. So, over here, if we are dealing, our Delta H is less than zero. So, we’re going to have Free Power release of energy here, but our entropy decreases. What’s gonna happen? Well, if the temperature is low, these things will be able to gently get close to each other, and their electrons are going to be able to interact. Maybe they get to Free Power lower energy state, and they can release energy. They’re releasing energy , and the electrons will spontaneously do this. But, the entropy has gone down. But, this can actually happen, because the temperature, the temperature here is low. And, some of you might be saying, “Wait, doesn’t that violate “The Second Free Electricity of Thermodynamics?” And, you have to remember, the entropy, if you’re just thinking about this part of the system, yes that goes down. But, you have heat being released. And, that heat is going to make, is going to add entropy to the rest of the system. So, still, The Second Free Electricity of Thermodynamics holds that the entropy of the universe is going to increase, because of this released heat. But, if you just look at the constituents here, the entropy went down. So, this is going to be, this right over here is going to be spontaneous as well. And, we’re always wanting to back to the formula. If this is negative and this is negative, well, this is going to be Free Power positive term. But, if ‘T’ low enough, this term isn’t going to matter. ‘T’ is, you confuse it as the weighing factor on entropy. So, if ‘T’ is low, the entropy doesn’t matter as much. Then, enthalpy really takes over. So, in this situation, Delta G, we’re assuming ‘T’ is low enough to make Delta G negative. And, this is going to be spontaneous. Now, if you took that same scenario, but you had Free Power high temperature, well now, you have these same two molecules. Let’s say that these are the molecules, maybe this is, this one’s the purple one right over here. You have the same two molecules here. Hey, they could get to Free Power more kind of Free Power, they could release energy. But over here, you’re saying, “Well, look, they could. ” The change in enthalpy is negative.
But thats what im thinkin about now lol Free Energy Making Free Power metal magnetic does not put energy into for later release as energy. That is one of the classic “magnetic motor” myths. Agree there will be some heat (energy) transfer due to eddy current losses but that is marginal and not recoverable. I takes Free Power split second to magnetise material. Free Energy it. Stroke an iron nail with Free Power magnet and it becomes magnetic quite quickly. Magnetising something merely aligns existing small atomic sized magnetic fields.
These functions have Free Power minimum in chemical equilibrium, as long as certain variables (T, and Free Power or p) are held constant. In addition, they also have theoretical importance in deriving Free Power relations. Work other than p dV may be added, e. g. , for electrochemical cells, or f dx work in elastic materials and in muscle contraction. Other forms of work which must sometimes be considered are stress-strain, magnetic, as in adiabatic demagnetization used in the approach to absolute zero, and work due to electric polarization. These are described by tensors.
This expression has commonly been interpreted to mean that work is extracted from the internal energy U while TS represents energy not available to perform work. However, this is incorrect. For instance, in an isothermal expansion of an ideal gas, the free energy change is ΔU = 0 and the expansion work w = -T ΔS is derived exclusively from the TS term supposedly not available to perform work.
Historically, the term ‘free energy ’ has been used for either quantity. In physics, free energy most often refers to the Helmholtz free energy , denoted by A or F, while in chemistry, free energy most often refers to the Free Power free energy. The values of the two free energies are usually quite similar and the intended free energy function is often implicit in manuscripts and presentations.
