The pressure p of a gas is plotted again...

The pressure `p` of a gas is plotted against its absolute temperature `T` for two different constant volumes, `V_(1)` and `V_(2)` when `V_(1) gt V_(2)`, the

A

curves have the same slope and do not intersect

B

curves must intersect at some point other than `T=0`

C

curves for `V_(2)` has a greater slope than that for `V_(1)`

D

curve for `V_(1)` has a greater slope than that for `V_(2)``

Text Solution

Verified by Experts

The correct Answer is:
C
At constant volumes `P prop T`
`P= "constant" T, PV= nRT :. P=(nR)/(V)T`
Slope `=m=(nR)/(V) :. V_(2) lt V_(1)`
`(m_(1))/(m_(2))= (V_(2))/(V_(1))` is curve for `V_(2)` has a greater slope than for `V_(1)`
