The total change in internal energy of the gas is the sum of the work done on the gas and the energy transferred to the gas from the reservoir.
Change in internal energy = Work done on the gas + Energy transferred to the gas
Change in internal energy = 900j + 1250j
Change in internal energy = 2150j
900j of work are done on a volume gas. The gas is placed next to a higher temperature reservoir, which gives 1250j of energy to the gas. What was the total change on the internal energy of the gas due to the reservoir and work done?
