A balloon filled with helium rises to a certain height at which it gets fully inflated to a volume of `10^(5)` litres. If at this altitude, temperature and atmospheric pressure are 268 K and `2xx10^(-3)` atm respectively, what weight of helium will be required to fully inflate the balloon ?

A He balloon is such that it can rise to a maximum height of 50 km above the Earth's surface. When the balloon rises to this height, its expansion reaches maximum with a volume of 10^(5)L . If the temperature and pressure of the air at this height are -10^(@)C and 1.8 mm Hg, respectively, then what mass of He gas will be required for the maximum expansion of the balloon?

A balloon contains 1500 m^(3) of helium at 27^(@)C and 4 atmospheric pressue. The volume of helium at -3^(@)C themperature and 2 atmospheric pressure will be

The volume of a gas measured at 27^@C and 1 atm pressure is 10 litres. To reduce the volume to 5 litres at 1 atm pressure, the temperature required is

The total kinetic energy of 8 litres of helium molecules at 5 atmosophere pressure will be (1 atmosphere =1.013xx10^(5) pascal)

A weather balloon filled with hydrogen at 1 atm and 300K has volume equal to 12000 litres. On ascending it reaches a place where temperature is 250K and pressure is 0.5atm. The volume of the balloon is:

A 10.0 litre container is filled with a gas to a pressure of 2.00 atm at 0^(@)C . At what temperature will the pressure inside the container be 2.50 atm ?
