Calculate the buoyant force on a helium filled balloon having a volume of 14000`cm^3`.

Calculation Of Buoyant Force

A helium filled balloon will float in air because

Assuming the same pressure in each case calculate the mass of hydrogen required to inflate a balloon to a certain volume V at 100^(@)C if 3.5 g helium is required to inflate the balloon to half the volume V at 25^(@)C .

Assuming the same pressure in each case calculate the mass of hydrogen requied to inflate a ballon to a certain volume V at 100^(@)C if 3.5 g helium is required to inflate the balloon to half the volume V at 25^(@)C .

A weather balloon is inflated with helium. The balloon has a volume of 100 m^(3) and it must be inflated to pressure of 0.10 atm. If 50 L gas cylinders of helium at a pressure of 100 atm are used, how many cylinders are needed? Assume that the temperature is constant.
