Solution
Verified by Toppr

The air in the balloon exerts pressure on the walls of the balloon. This is accordance with the kinetic molecular theory of gases which state that the pressure exerted by the gas is equal to the pressure applied by the gas molecule on the walls of container.

Q5
A spherical balloon initially contains 1 mole air at 1 atm, then it is further filled with air till pressure increases to 3 atm. The initial diameter of the balloon is 1 m and the pressure at each state is directly proportional to diameter of the balloon. Answer the following questions.(a) Find out number of moles of air added in balloon to change the pressure from 1 atm to 3 atm. (b) If balloon burst either pressure increases to 7 atm or volume increases to 360πm3.Calculate the number of moles of air that must be added after initial condition to burst the balloon.
