2. A spherical balloon is made from a material whose mass is 3.30 kg. The thickness of the material is negligible compared to the 1.45 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 295 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m3 and the molar mass of helium is 4.0026x10-3 kg/mol. Find the absolute pressure of the helium gas. Pa

The balloon is filled with helium (He) at a temperature of 300 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m3 and the molar mass of helium is 4.0026x10 kg/mol. Find the absolute pressure of the helium gas. Pa 60 ssf6
A hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be?

1. People buying food in sealed bags at high elevation often notice that the bags are puffed up because the air inside has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of 22.0 C. When opened at a summer picnic in Santa Fe, New Mexico, at a temperature of 32.0 C, the volume of air in the bag is 1.13 times its original volume. What is the pressure of the air P Santa Fe? = 0.079 Santa Fe X atm
2. A spherical balloon is made from a material whose mass is 2.90 kg. The thickness of the material is negligible compared to the 1.25 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 300 K and just floats in air, neither rising nor falling.

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.
