5. (Ideal Gas Law) A balloon in daytime at 1 bar and 20°C has a volume of 1 m³. The balloon is cooled to 0°C in night-time. Assuming constant pressure, thermal equilibrium of the balloon with the ambient atmosphere, and ideal nitrogen gas (c=0.743 kJ/kg/K, molar mass: M=28.02 g/mole) in the balloon, please find the following answers step-by-step: What is the Nitrogen mass in the balloon? What is the balloon volume at night-time? How much work has the balloon done to the environment from daytime to night-time? What is the total internal energy change of the balloon from daytime to night-time? How much heat has the balloon released to the environment from daytime to night-time? (1) (2) (3) (4) (5)
