Question

The pressure on 2.50L of anaesthetic gas is changed from 760mm Hg to 304mm Hg.
What will be the new volume if the temperature remains constant?​

Answer 1

Using Boyle’s Law, P1V1=P2V2(where P1 and V1 are initial pressure and volume, and P2 and V2 are final pressure and volume).

We need to find the final volume, therefore,

V2=P1V1/P2

V2=340*250/50

V2=1700ml

Therefore, the volume will be 1700ml when pressure is reduced to 50kPa.

Answer 2

Answer:

Using Boyle's Law, P1V1=P2V2(where P1 and V1 are initial pressure and volume, and P2 and V2 are final pressure and volume).

We need to find the final volume, therefore,

V2-P1V1/P2

V2-340*250/50

V2=1700ml
