The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is475 m3. To what temperature must the air in the balloon be heated before the balloon will liftoff? (Air density at 10.0°C is 1.25 kg/m3.) 1 K
A weather balloon contains 12.0 m2 of hydrogen gas when the balloon is released from a location at which the temperature is 22.0°C
3) A weather balloon contains 12.0 m2 of hydrogen gas when the balloon is released from a location at which the temperature is 22.0°C and the ambient air pressure is 101 kPa. The balloon rises to a higher altitude where the temperature is -30.0°C and the ambient air pressure is 20.0 kPa. If the balloon is free to expand so that the pressure of the gas inside is equal to the ambient pressure outside, what is the new volume of the...

Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

A spherical balloon is made from a material whose mass is 3.40 kg. The thickness of the material is negligible compared to the 1.40 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 280 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 4.0026×10-3 kg/mol. Find the absolute pressure of the helium gas.

A spherical balloon of 11 m in diameter is filled with helium of gas constant, R = 2.0771 kJ/kg.K at T = 15 oC and P = 100 kPa. If the balloon is used to lift load in the air of 1.25 kg/m3 density, how much load in Newtons (in addition to its own weight) can the balloon carry. Ignore drag force and weight of the balloon’s fabric? (Volume of a sphere = 4 3 ??^3 ).
