The pressure `p` for a gas is plotted against its absolute temperature `T` for two different volumes `V_(1)` and `V_(2)`. If `p` is plotted on `y-` axis and `T` on `x-`axis, then

Options

A. the curve for `V_(1)` has greater slope than that for `V_(2)`
B. the curve for `V_(2)` has greater slope than that for `V_(1)`
C. both curves have same slope
D. the curves intersect at some point other than `T = 0`

Answer

A

Explanation

`PV = nRT , PV prop T , PV prop T, V prop (T)/(P)`
Slope of the graph gives volume of the gas Keep `'T'` constant
`Tantheta_(1) gt Tantheta_(2) :. V_(1) gt V_(2)`
