The two bulbs of volume 5 litre and 10 litre containingan ideal gas at

1.	The two bulbs of volume 5 litre and 10 litre containingan ideal gas at 9 atm and 6 atm respectively areconnected. What is the final pressure in the twobulbs if the temperature remains constant?(1) 15 atm(3) 12 atm(2) 7 atm(4) 21 atnm
Answer» We will use gas law as P1V1 +P2V2 = PfVf ..... ( Vf = V1+V2) => 59+106 = Pf(10+5)=> 45+60 = Pf(15)=> Pf = 105/15 = 7atm option 2

Answer»

We will use gas law as

P1V1 +P2V2 = PfVf ..... ( Vf = V1+V2)

=> 5*9+10*6 = Pf(10+5)=> 45+60 = Pf(15)=> Pf = 105/15 = 7atm

option 2
