(first law of thermodynamics)
{"Image DocumentName": "(first law of thermodynamics)", "Image ImageDescription": "Add a quantity of heat Q to a system and the system does no work during the process, the internal energy. increases by an amount equal to Q : \uf044U = Q. When a system does work W by expanding against. its surroundings and no heat is added during the. process, energy leaves the system and the internal energy decreases. When both heat transfer and work occur, the total change in internal energy is. (first law of thermodynamics) This means that the change in internal energy of a system is equal to the sum of the energy transferred across the system boundary by heat and the energy transferred by work.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
