A balloon containing 1 mole air at 1 atm initially is filled further with air till pressure increases to 3 atm. The intialdiameter of the balloon is 1 m and the pressure at each state is proportion to diameter of the balloon. Calculate ( a) No.of moles of air added to change the pressure from 1 atm to 3 atm. ( b) balloon will burstif either pressure increases to 7 atm or volume increases to 36 pi m^(3).Calculate the number of moles of air that must be added after initial condition to burst the balloon.

1.	A balloon containing 1 mole air at 1 atm initially is filled further with air till pressure increases to 3 atm. The intialdiameter of the balloon is 1 m and the pressure at each state is proportion to diameter of the balloon. Calculate ( a) No.of moles of air added to change the pressure from 1 atm to 3 atm. ( b) balloon will burstif either pressure increases to 7 atm or volume increases to 36 pi m^(3).Calculate the number of moles of air that must be added after initial condition to burst the balloon.
Answer» ANSWER :`P PROP d; P =KD`& `k = ( 1 atm)/( 1 "METER"); `(i) 80; (b) 1295 moles
