Question

A steel cylinder of 4 Ltr., capacity contains hydrogen gas ‘X’ atm. 10 cycle tubes of each 2 Ltr, capacity are to be filled with gas at a pressure of 1 atm at the same temperature, then ‘X’ is

Answer 1

Given:

Volume of Steel cylinder, V1 = 4 litre

Volume of 1 cycle tube = 2 litre

Pressure of cycle tube, P2 = 1 atm

To Find:

Pressure of hydrogen gas in steel cylinder, i.e., P1 = X

Calculation:

- Volume of 10 cycle tubes, V2 = 10 × 2 = 20 litre

- We know the relation:

P1 × V1 = P2 × V2

⇒ X × 4  = 1 × 20

⇒ X = 5 atm

- Hence, the pressure of hydrogen gas in steel cylinder is X = 5 atm.
