A balloon is 1m in diameter and contain air at 25^(@)C and 1 bar pressure. It is filled with air isothermally and reversibly until the pressure reaches 5bar. Assume pressure is propotional to diameter of ballon. Calulate work done by air (atm ,m^(3))

A balloon containing 1 mole air at 1 atm initially is filled further with air till pressure increases to 4 atm. The intial diameter of the ballon is 1 m and the pressure at each stage is proportional to diameter of the balloon. How many moles of air added to change the pressure from 1 atm to 4 atm.

A balloon containing 1 mole air at 1 atm initially is filled further with air till pressure increases to 4 atm. The intial diameter of the ballon is 1 m and the pressure at each stage is proportional to diameter of the balloon. How many moles of air added to change the pressure from 1 atm to 4 atm.

A balloon is filled with one mole of helium at 0^@C and 1 bar pressure. It will burst if pressure is decreased to 0.2 bar. What is the maximum volume of balloon?

A spherical balloon contains air at pressure P_(1) and is placed in vacuum. It has an initial diameter of D_(1) . The balloon is heated until its diameter becomes D_(2) = 2D_(1) . It is known that pressure in the balloon is proportional to its diameter. Calculate the work done by the gas in expansion.

Iron react with HCl at 25^@C & 1 bar pressure & give FeCl_2 & H_2 (g), then find magnitude of work done (in KJ) in this process at 1 bar constant pressure

A balloon has maximum capacity of 20 L. At one atmospheric pressure 10 L of air is filled in the ballon. It will burst when the external pressure is reduced to (assume isothermal conditions)

A balloon is filled with Hydrogen at room temperature. It will burst if pressure is 0.2 bar. If at 1 bar pressure the gas occupies 2.27L volume, at which volume balloon will burst ?

A spherical balloon is filled with air at 2 atm pressure. What pressure is to exerted on the balloon from outside so that its diameter will be reduced to half of its initial diameter?
