Document Summary
Thermodynamics - study of energy: energy --> work +/or heat, work --> move object that has an, heat --> more ke movement. Interaction between charged partials --> q therefore if atom 1 is porton then its positvily charged. If eel postive, therefore same charge, and repel o o: the lower the eel the more stable the partials are. So e universe = 0 joule = l kg m2/s2 --> 2 kg at 1m/s = 1 j. Amount of e raise temp 1 c of 1 g of h2o. Internal energy --> denoted as e is the energy of the system (ke and pe) E > 0 , so internal energy is increasing q>0 & w>0 heat gained work done on the system. E < 0 , so internal energy is decreasing. Esystem - extensive property proportional to the total quanity of matter. State function dependent on the curent state not path dependent. Enthalpy heat flow that occurs under constant pressure.
