An ideal gas is compressed from a volume of Vi = 5.00 L to a volume of Vf = 3.00 L while in thermal contact with a heat reservoir at T  = 295 K as in Figure P12.21. During the compression process, the piston moves down a distance of d  = 0.130 m under the action of an average external force of F  = 25.0 kN. Find (a) the work done on the gas, (b) the change in internal energy of the gas, and (c) the thermal energy exchanged between the gas and the reservoir. (d) If the gas is thermally insulated so no thermal energy could be exchanged, what would happen to the temperature of the gas during the compression?

Step 2


Since, the ideal gas is in contact with the heat reservoir; the compression of ideal gas is an isothermal process. Internal energy of an ideal gas is only depends of th...
