Then read the discussions about the Gibbs free energy on this site they address all of these points. It decreases, not increases, with increasing entropy. When energy is transferred from a hotter object to a colder one, some of. The cube and the room will exchange, at any infinitesimal moment, heat $Q$, so the cube will gain entropy $\frac$, because it is heat that cannot be recovered from going between the initial and final states and therefore doesn't fulfil our requirement for an isolated system. asked at 6:07 UnrulyTank 308 1 7 1 Read the Wikipedia article on Gibbs free energy, which is likely what your notes refer to. The increase in entropy is related to the concept of heat transfer and energy flow. Where in the video did Sal say that atoms squish I recommend watching the Vsause video, 'You can't touch anything. The increase in entropy occurs because the decomposition of dinitrogen tetroxide to nitrogen dioxide results in an increase in the number of gas molecules. That means that the subsystems of the whole system are increasing their entropy by exchanging heat with each other and since entropy is extensive the system as whole is increasing entropy. 6 years ago Atoms really can't squish against each other because the negative electrons will repel each other. All what I'm really saying is that the room as whole is not at equilibrium meaning that the system is exchanging heat, etc. This may seem like a special case, but it's not. The ice will melt and the total entropy inside the room will increase. ![]() Let's say that the room is the isolated system. Because the change in entropy is Q/T, there is a larger change in S S at lower temperatures (smaller T). ![]() Take a room and an ice cube as an example.
