Question

A sample of oxygen has volume of 800 ml at a pressure of 740 bar what additional pressure is required to reduce the volume of 548

Answer 1

ANSWER

According to Boyle's law, at constant temperature,

P∝

V

1

∴

P

2

P

1

=

V

1

V

2

Given that:-

P

1

=740mm

${V}_{1} = 190 \; mL$$

P

2

=760mm

V

2

=?

∴

760

740

=

190

V

2

⇒V

2

=

760

740×190

⇒V

2

=185mL

Hence, at 760 mm pressure, volume will be 185 mL.
