At 1 atm pressure and 25' temperature, a ballon weighing 25 Kg is packed with 342.6 28 kg of helium. What will be its pay load if it displaced 2554 kg of air?
Correct answer: A. 2186.4 kg
- A. 2186.4 kg
- B. 2896.6 kg
- C. 2129.6 kg
- D. 2211.4 kg
Explanation
Total mass of the balloon= 25kg + 342.6 kg =367.6 kg Payload is the carrying capacity, Thus, Pay load = Mass of displaced air - Total mass of balloon= 2554 kg - 367.6 kg = 2186.4 kg

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.

At 100.C and 1 atm, if the density of liquid water is 1.0 g/cc and that of water vapour is 0.0006 g/cc, then the volume occupied by water molecule in one litre of steam at that temperature is:
Blood circulation in human body provides O2 and emits CO2. The concentration of O2 and CO2 is variable, but on an average 0.02 g O2 and 0.08 g CO2 present in an 100 ml of blood. Find the volume of O2 and CO2 in the blood of human (assuming 9.5 L) at 1 atm and 37oC body temperature.
A vessel has N2 gas and water vapours at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The contents of this vessel are transferred to another vessel having one third of the capacity of original volume, completely at the same temperature. The total pressure of this system in the new vessel is:
Under what conditions the density of an ideal gas will be maximum at:
A graph between pressure and product of pressure and volume at constant temperature and number of moles gives:
If both temperature and volume of a gas are doubled, the pressure:
