Air is contained in a piston cylinder arrangement as shown in Fig. The piston can be assumed to be massless, frictionless, and perfectly insulated. 10 kg of dry ice (solid CO2) is placed on top of the piston. The initial conditions for air inside the cylinder are Pı=121 kPa, Tı= 300 K. Dry ice sublimates gradually, and its mass reduces to 5 kg. Ambient air is always at room temperature (27°C) and atmospheric pressure. (Given: R=287 J/kg ·K, g = 9.8 m/s², Cp/Cy for air = 1.4; Neglect all heat transfer to the dry %3D ice block.)
