In the first law of thermodynamics what is q
WebMay 11, 2024 · The first law of thermodynamics can be expressed mathematically as. d U = d ¯ Q + d ¯ W or as Δ U = Δ Q + Δ W. So lets suppose we had some system and suppose 80 J of heat flow into the system, and the system does 30 J of work. Would the change in internal energy of the system be expressed as. Δ U = 80 J − 30 J = 50 J. or as. Weba) Conservation of energy. b) Conservation of mass. c) Conservation of momentum. d) Conservation of work. View Answer. 3. If 315cal of heat is given to the system, and the …
