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)

_ is generally determined by the consumer rather than by the producer. In other words, if a customer perceives that he receives more in benefits than what he has to pay for those benefits (or, he gets more in benefits than what he perceives it costs him to acquire those benefits), then he is probably going to be fairly happy with that product in relation to its cost.
