Question

A steel cylinder of internal volume 20 litres is filled with hydrogen at 29 atmospheric pressure. If hydrogen is used to fill a balloon at 1.25 atmospheric pressure at the same temperature, what volume will the gas occupy?

Answer 1

Answer:

According to Boyle's law, at constant temperature, pressure exerted by a gas is inversely proportional to its volume.

Hence, mathematically we can write as:

PV = k 

Where k is constant. 

So,we can write as,

P1V1 = P2V2  .................(i)

Here 1 is used for representing initial condition and 2 is used for final conditions. 

P1 = 29 atm

P2 = 1.25 atm

V1 = 20 L 

Substitute above values in equation (i)

V2 = 20 x 29 / 1.25 

= 464 L
