A. An air compressor fills a tank to a gage pressure of 100 psi. The barometric pressure is 751 millimeters of mercury. What is the absolute pressure in the tank in kPa?

B. The air in the tank is bled out through a valve, the valve is closed, and the tank and its contents sit out overnight. The temperature drops, while the barometric pressure increases to 775 millimeters of mercury. A vacuum gage on the tank in the morning reads 1.2 inches of mercury. What is the absolute pressure in the tank in kPa?
