The volume-temperature graphs of a given mass of an ideal gas at constant pressures are shown below. What is the correct order of pressures ?

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

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

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

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

Text Solution

Verified by Experts

The correct Answer is:

Drawing a constant temperature line parallel to .V. axis, the isobar at higher volumes will be at lower pressure as `P prop 1/V` at constant temperature.
