Question

4. 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 ?
[Ans. 464 litres​

Answer 1

Answer:

According to Boyle's law

Explanation:

P_1V_1= P_2V_2P

​  

V

​  

=P  

2

​  

V

​  

 

if P_1 = 29 \ atm, V_1 = 20l, P_2= 1.25\ atmP  

1

​  

=29 atm,V  

1

​  

=20l,P  

2

​  

=1.25 atm, then V_2= \dfrac {29 \times 20}{1.25} = 464\ LV

​  

=  

1.25

29×20

​  

=464 L
