Calculate the amount of work necessary for the reversible compression of steam from 1 bar to 10 bar. The compression is to take place in a cylinder fitted with a weightless piston at the constant temperature of 500 °C. Under these conditions we have a superheated vapor. Report your answer in units of kJ/kg using three decimal places. As you check your work, note that here we have compression from 1 bar to 10 bar under constant temperature. We would expect the volume of the system to decrease. Use this to check the sign (positive or negative) of your computed work.
