Webb19 feb. 2024 · The first law states that: d U s y s t e m = δ Q − p i n t d V I "understand" this formulation if the pressure p is the pressure of the system on the surroundings, i.e. the internal pressure. Sometimes however the first law is formulated with the external pressure. I understand that you can say this, because ultimately energy is conserved: WebbIn simple words, the first law of thermodynamics is defined as Heat supplied to system = sum of the changes in internal energy + work done by the system The first law of thermodynamics equation is represented by ΔU =ΔQ – ΔW ΔU represents a change in internal energy of the thermodynamic system ΔQ represents heat given to the system
