Lower temperature, energy in the form of heat to travel from our body to the water, which means body is losing energy, and the cup of water gaining that energy.

Now when i was ng about heat transfer, i didn't quite difference between heat and temperature, so i just go ahead and briefly discuss what the difference is.

And since the system achieve its lowest energy possible, if no opposing force, the gradient disappear, so this is the basis transfer.

So to summarize, the point want to underscore here is that while temperature absolute measure of energy, there is really no such an absolute heat content.

Heat should always bed as heat transfer, because it is measuring of heat that is either lost or gained.

It's also important to heat transfer occurs between a system surroundings, which i'm going iate as surr.

Now as i talked , we can't really attribute an of heat content to either the the surroundings, but what we can say is, ion does this heat transfer occur in?

So the way that ists kind of denote heat transfer is with ase letter q.

And so in the our system, which is our hand becoming colder, the way that this would d is with a minus q, because heat energy lost from the system.

To state this generally, it's fair to say that the is either lost or gained by the system is opposite in magnitude to the heat that' lost or absorbed by the analogy for gibbs free energyenthalpyup nextenthalpy.
