Question

• At 300 K, a steel cylinder of internal volume of 20dm3
is filled with hydrogen at a pressure of 25 atmospheres.
If hydrogen is used to fill a balloon of 1.25 atmosphere
pressure at 27° c, what volume will the gas fill?

​

Answer 1

Explanation:

According to Boyle's law, P

1

V

1

=P

2

V

2

if P

1

=29 atm,V

1

=20l,P

2

=1.25 atm, then V

2

=

1.25

29×20

=464 L
