2-An automobile wheel contains air with a pressure of 3x10 'Pa at 25 ° C. The sipop cover was removed and the air was expanded adiabatically against an external pressure of 10 'Pa. What is the final temperature of the gas in the wheel? (It should be taken into account that the gas behaves ideally and the Cp value for air is 7 / 2R)

Shown in the figure, an insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains an indeal gas, and the other part is evacuated. The partition is then removed, and the gas expands into the entire tank. At the initial state, the mass of the gas is m= 4.00kg, initial pressure is p1 = 600.00 kPa, initial temperature is T1 = 300.00 K. The gas constant is R = 0.2870 kJ/(kg·K). (The internal energy can be determined by the equation ΔU=m·cv·(T2-T1), where cv = 0.7180 kJ/(kg·K) is the specific heat at the constant volume.)

Air as an ideal gas is contained in a piston/cylinder system constrained by a non-linear spring. Initially the gas in the cylinder is at 100 kPa, which is balanced by the atmospheric pressure outside of the cylinder (the weight of the piston is negligible). The force on the spring at the start is zero. The spring force is F=kx². k=600. kNt/m². The cross-sectional area of the piston is 1 m², the initial volume is 1 m³, and the initial temperature is 300 K. Heat is added until the volume of the gas has expanded to 1.5 m³. Find: (a) The work done by the gas on the face of the piston (kJ). (b) The final temperature (K). (c) The amount of heat added (kJ). Hint: This problem is easiest if you calculate the spring work and the atmospheric work separately. Air V₁=1.0 m³ Piston Area = 1.0 m² T₁=300 K P₁=100 kPa Atmospheric P on upper piston face= 100 kPa
