air is filled in a bottle and it is corked at 35° C. If the cork can come out at 3atm pressure, then upto what temperature should the bottle be heated in order to remove the cork?

615 ° C

Your Answer

P1 V1 / T1 = P2 V2 / T2

Volume is constant (bottle volume). So,

P1 / T1 = P2 / T2
1 / (273+35) = 3 / T2

So temperature to be heated is,

651 C.
At which bottle would have vaporized.
