A pioneer aeronaut is planning the design of a hot-air balloon. What volume of air, in m³, at 100°C should be used if the balloon is to have a lifting power of 200 kg. The ambient temperature and pressure are 25°C and 1 atm, and the average molecular weight of air is 29 g/mol, whereas that of the hot air is 32 g/mol (due to the presence of some carbon dioxide). (Note that the lifting power is equal to the difference in the masses, for a given volume, of the surrounding air and the gas (hot air) inside the balloon.)

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 43.0cm wide and 51.6cm high. The maximum safe pressure inside the vessel has been measured to be 5.20MPa. For a certain reaction the vessel may contain up to 9.03kg of chlorine pentafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius.
