How can the internal energy system change
Web27 de fev. de 2016 · My professor says the internal energy of a system can be calculated as U = n T c v. Now I always thought that we could only calculate a change in internal energy Δ U = n c v Δ T.

This results in the following sign convention for a transfer of heat or work: If heat or work is transferred into a thermodynamic system, these amounts of energy are counted positively (Q> or W>0).
