1) The pressure gage on a 2.5 m³ oxygen tank reads 500 kPa. Determine the temperature in the tank given the amount of oxygen in the tank is 19 kg and the atmospheric pressure is 97 kPa. 2) A spherical balloon with a diameter of 10 m is filled with helium at 200 kPa. The amount of helium in the balloon is 125 kg, determine the temperature of the balloon. 3) A rigid tank with unknown volume is divided into two sections by a partition. One side of the tank contains an ideal gas at 930 C. The other side is evacuated and has a volume twice the size of the part containing the gas. The partition is now removed, and the gas expands to fill the entire tank. In addition, heat is applied to the gas until the pressure equals the initial pressure. Determine the final temperature of the gas.

Answer the following questions with solution/ detailed explanation: 1. The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa.
