Please help and show work. 

Patm-101kPa; g=9.81m/s? mpiston=50kg; Apiston=49.5cm? Mystery substance; initial temperature is 10°C
Transcribed Image Text:Patm-101kPa; g=9.81m/s? mpiston=50kg; Apiston=49.5cm? Mystery substance; initial temperature is 10°C
What system phase(s) is(are) present if the temperature is 20°C? What amount of heat transfer occurred between the system and surroundings? Enter a numerical value in kJ. A fire breaks out near the assembly, and the temperature of the substance rises. The piston hits the stops when the volume reaches 1.5m3. The temperature continues to rise. By the time the tank is moved to a safe location, the pressure reaches 3bar and the temperature is 212°C; the internal energy is 619 kJ/kg at this state. How much work is done by the system during the fire? Enter a numerical value in kj. What amount of heat transfer occurred between the system and surroundings during the fire? Enter a numerical value in k).
