- Liquid nitrogen has a boiling point of−190.52◦C at atmospheric pressure.Express this temperature in degreesFahrenheit.Answer in units of ◦F Express this temperature in Kelvin.Answer in units of K.A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
