A metal tank contains air at 20 C and 400 kPa. The tank volume is 5 m³. It is connected through a valve to another tank containing 7 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.

Required information Jobe Concrete Products placed a new sand sifter into production 3 years ago. It had an installed cost of $100,000, a life of 5 years, and an anticipated salvage of $20,000. Book depreciation charges for the 3 years are $42,000, $18,000, and $22,000, respectively. If the sifter's market value today is $20,000, determine the difference between its current book value and its market value. The difference between its current book value and its market value is determined to be $
