Chapter 2.8, Problem 40P
Water is being heated in a closed pan on top of a range while being stirred by a paddle wheel. During the process, 30 kJ of heat is transferred to the water, and 5 kJ of heat is lost to the surrounding air. The paddle-wheel work amounts to 500 N·m. Determine the final energy of the system if its initial energy is 12.5 kJ.

Nitrogen with a mass of 4.68 kg expands at constant pressure. The initial pressure and temperature in the piston-cylinder system are 172 kPa and 21.4°C, respectively. Because of the heat transfer, the system reached a final temperature of 205.7°C. Compute for the work in kJ.Answe r must be in 3 decimal places
Nitrogen with a mass of 3.82 kg expands at constant pressure. The initial pressure and temperature in the piston-cylinder system are 172 kPa and 23.4°C, respectively. Because of the heat transfer, the system reached a final temperature of 206.4°C. Compute for the work in kl. Answer in 3 decimal places.
One kilogram of gas is contained in a piston-cylinder apparatus. The gas is then heated with 78.2 kJ of energy while a mixing device delivers shaft work to the gas in the amount of 18.5 kJ. During the process the specific internal energy of the gas decreased from 2709.9 kJ/kg to 2659.6 kJ/kg. If there is no significant change in the kinetic and potential energy of the gas, determine the amount of work (in kJ) accompanying the volume change for the process. If the constant holding pressure is equivalent to the atmospheric pressure, calculate the change in volume (in m³) for the gas.
