An ideal gas is in contact with a heat reservoir to that it remains at a constant temperature of 300.0 K.The gas is compressed from 24.0 L to 14.0 L.The mechanical device that operating the piston to compress the gas expends 5.00 kJ of energy.How much heat flows between the gas and the heat reservoir?

The first law of thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. In this case, the change in internal energy is zero because the temperature remains constant. Therefore, the heat added to the system must be equal to the work done by the system, which is -5.00 kJ.
