1st Law of Thermodynamics - Chemistry LibreTexts

WitrynaThe first law is a statement of energy conservation. It tells us that a system can exchange energy with its surroundings by the transmission of heat and by the performance of work. The net energy exchanged is then equal to the change in the total mechanical energy of the molecules of the system (i.e., the system’s internal energy). WitrynaWhat is interesting about gravitational potential energy is that the zero is chosen arbitrarily. In other words, we are free to choose any vertical level as the location where h = 0 h=0 h = 0 h, equals, 0.For simple mechanics problems, a convenient zero point would be at the floor of the laboratory or at the surface of a table. lg apt headphones
