Aha, now everything is clear in my mind.

It feels weird that in an ISOCHORIC process the enthalpy(the potential to do work? Can I say that way?) increases more than the heat supplied...so I get more work(energy) than I gave in(in the form of heat) Yes, I know that I'm wrong but I was having trouble seeing this. But thanks for the...

Hi, I know enthalpy is used a lot to calculate isobaric processes, but what about isochoric ones? For example, if I have gas in a piston and I add heat at constant VOLUME. I know that Q=\Delta U But since H=U+PV or \Delta H=\Delta U + \Delta PV I see that although V is constant P is not, it...

Thermo is kinda complex, since it's not based on simple laws like mechanics that work on every situation

I'm not a thermo master or anything but let's see You don't need to do it in one big jump, yes when you do it fast it's adiabatic because there will be no time to exchange heat with the surroundings but if you use an insulating container you will also not exchange heat and it will be adiabatic...

Hmm, I get it. Now let's see with my math is right If the pressure outside is 1atm, and I'm doing part of the work I can't calculate the work done by the gas simply integrating(or multiplying since it's constant) the dV times the P. So could I calculate it by removing the pressure caused by my...

If the system is adiabatic it won't be able to release, absorb heat, and then the internal energy will not be constant. That is, if you compress(give work) to an adiabatic system it will increase U and it will get hotter. And I think you got it backwards, if the system does work it needs to...

Well I tried that lol Yes, it seems like I'm doing a good amount of work, but isn't the gas doing anything? Maybe something I can't detect with such crude experiment

Hi, I'm studying thermodynamics and I got a question, it's not a homework or anything, it simply isn't covered in my book and it got me thinking I know that if I have cylinder filled with gas, with a piston on top and there are weights on it maintaining an equilibrium if I remove the weights...
