A gas trapped in a piston-cylinder device is subjected to the energy interactions shown in the accompanying figure for 30 seconds: the electric resistance heater draws 0.1 amp from a 100 V source, the paddle wheel turns at 60 rpm with the shaft transmitting a torque of 5 N-m and 1 kJ of heat is transferred into the gas from the candle. The volume of the gas increases by 6 L during the process. If the atmospheric pressure is 100 kPa and the piston can be considered weightless, determine
(a) WB.
(b) Wsh.
(c) Wel.
(d) Wnet.
(e) Enet that is added to the system.
