Task 3
A 3 m³ tank contains air at 15 C and 400 kPa is connected through a valve to another tank containing
5 kg of air at 40 C and 300 kPa. After 10 minutes, the valve is opened, and the whole system will
reach thermal equilibrium with the surroundings (T= 25 C). Determine the volume of the second
tank and the final pressure of air. Explain the relationships between system constants for a perfect
gas. In addition, discuss under what conditions is the ideal-gas assumption suitable for real gases?
Two kilograms of water is contained in a piston/cylinder (Fig. P3.143) loaded with a linear spring and the outside atmosphere. Initially the water is at 200 kPa, V = 0.2 m3. If the piston just hits the upper stops, the volume is 0.8 m3 and T = 600°C. Heat is now added until the pressure reaches 1.2 MPa. Show the P−V diagram, and find the work and heat transfer for the process.
A spring-loaded piston-cylinder device contains m= 1kg of carbon dioxide. Initially, the spring has no force on the piston and P₁ = 500kPa, T₁=150K, V₁ = 0.1m³.

Heat is transferred to the gas, causing the piston to rise and to compress the spring. At the state 2, T₂=900K, V₂=0.3m³. The gas is an ideal gas.
