Question

cylinder of 25 litres capacity contains a gas at 100 atmosphere pressure. How many flasks of 250 cm³ capacity can be filled from it at 1 atmosphere pressure, temperature remaining constant ?​

Answer 1

Answer:

V1 = 25 L

P1 = 100 atm

V2 = ?

P2 = 1 atm

Using Boyle's Law,

P1 * V1 = P2 * V2

V2 = P1 * V1 / P2

    = 25 * 100/ 1

     = 2500

V2 = 2500 L

No of flasks = 2500 * 1000 / 250         [Since 1 L = 1000 cm3]

                   = 10,000
