1-kg water in a frictionless piston-cylinder device is initially at 250 degrees Celsius and 300 kPa (state1). A total of 700 kJ of work is done on the water in order to isothermally reduce its volume to 1/20 of its initial volume (state 2). Determine the magnitude and direction of the heat transfer involved in this process.
