A plot of volume (V) versus temperature ...

A plot of volume (V) versus temperature (T) for a gas at constant pressure is a straight line passing through the origin. The plots at different values of pressure are shown in figure. Which of the following order of pressure is correct for this gas ?

A

`p_(1) gt p_(2) gt p_(3) gt p_(4)`

B

`p_(1) = p_(2) = p_(3) = p_(4)`

C

`p_(1) lt p_(2) lt p_(3) lt p_(4)`

D

`p_(1) lt p_(2) = p_(3) lt p_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
At a particular temperature, `pV =` constant
`{:("Thus,",p_(1)V_(1)=p_(2)V_(2)=p_(3)V_(3)=p_(4)V_(4)),("As",V_(1) gt V_(2) gt V_(3) gt V_(4)),("Therefore,",p_(1) lt p_(2) lt p_(3) lt p_(4)):}`
