A substance is contained in a piston cylinder assembly with properties as described by the attached saturation and superheated vapor tables. The piston has a mass of 50kg and face area of 49.5 square-centimeters. The assembly contains 5kg of a mystery substance and is stored outside. Overnight the temperature drops to 10°C, but the temperature rises during the afternoon. Mechanical stops prevent the piston from leaving the cylinder. Take the substance to be the system.

Question
A substance is contained in a piston cylinder assembly with properties as described by the attached saturation and superheated vapor tables. The piston has a mass of 50kg and face area of 49.5 square-centimeters. The assembly contains 5kg of a mystery substance and is stored outside. Overnight the temperature drops to 10°C, but the temperature rises during the afternoon.
Transcribed Image Text:A substance is contained in a piston cylinder assembly with properties as described by the
attached saturation and superheated vapor tables. The assembly contains 5kg of the
substance and is stored outside. Overnight the temperature drops to 10°C, but the
temperature rises during the afternoon. Mechanical stops prevent the piston from leaving
the cylinder. Take the substance to be the system.
Patm=101kPa; g=9.81m/s?
mpiston=10kg; Apiston=0.99m?
What is the pressure of the system in bar for the configuration shown in the figure?
What system phase(s) is(are) present if the temperature is 10°C?
Mystery substance;
initial temperature is 10°C
During the day, the temperature rises to 20°C and there is still space to expand before the
piston reaches the stops. What is the new system volume in m³?
How much work is done by the system on the surroundings to expand from 10°C to 20°C? Enter a numerical value in kJ.
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 kJ.
