Question 6 Number Problems

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:

= 20 litre

P = 29 atm

P1 = 1.25 atm

V1 =?

T = T1

By gas equation PV/T = P1V1/T1

= 29 x 20/T

= 1.25 x V1/T

V1 = 464 litres
