As a result of some process, the internal energy of a system is increased. according to the first law of thermodynamics, au-q-w. how can one tell that the increase was due to orderly macroscopic work w or due to the flow of energy through disorderly microscopic means q? o (i) by measuring the temperature of the system before and after the process. ()by measuring the temperature of the surroundings before and after the proces o it is not possible to distinguish between w and q o both (i) and (ii) are correct.
