Hello, my name is Roberto and I am engineering student from Spain. I am a new member in the forum and I don´t know if this is the right site to present me but I want to use this moment to say hello to the comunity.
I have a doubt with a thermodinamic exercise.I have an adiabatic cylinder with double chamber separated by a piston diatermano. In the chamber of the left there is a resistance initially turned off and the system is in thermodynamic equilibrium. When turn on the resistance the piston moves to reach a new equilibrium.My doubt is what are the right ecuations:
-Total energy balance \Delta U_ {total}=-W_ {elec}
-A chamber \Delta U_A=Q-W_{exp}-W_{elec} or \Delta U_A=-W_{exp}-W_{elec}
-B chamber \Delta U_B=Q-W_{exp} or \Delta U_B=-W_{exp}
Thank you very much and I sorry if something is wrong.
