Question
A gas filled in a piston-cylinder arrangement as shown in Figure 1 has a volume of 0.09 m³ at its initial
equilibrium state. The gas is slowly heated through the bottom of the cylinder that allowed for the gas to
expand at constant-pressure of 2095 kPa to a volume of 1.23 m°. The change in internal energy of the
gas is 0.24 kJ. Ignoring the friction between the piston and the cylinder and assuming the atmospheric
pressure any value from 90 to 110 kPa,
of
(a) Calculate the mass of the piston if the area of the piston is 0.047 m2
(b) For the gas as a system, evaluate work and heat transfer, each in kJ
(c) For the piston as a system, evaluate work and change in potential energy, each in kJ
