In the following `V-T` diagram what is the relation between `P_(1)` and `P_(2)`.

A

`P_(2)=P_(1)`

B

`P_(2) gt P_(1)`

C

`P_(2) lt P_(1)`

D

cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
C
Ideal gas equation
PV = nRT
`and (V)/(T) prop (1)/(P)` by equation
and by graph `(V)/(T)=tan theta`
`therefore (1)/(P) prop tan theta`
`theta uarr, tan thetauarr, P darr`
`therefore P_(1) gt P_(2)`
