As we learnt in

Equation of state -

The relation between the  Thermodynamics variable (P, V, T) of the system is called equation of state.

- wherein

PV=nRT

 

 

 

For an ideal gas

PV=nRT

or      V=(\frac{nR}{P})T

For V-T graph slope  =\frac{nR}{P}

From figure , tan\Theta _2>tan\Theta _1

or     \frac{nR}{P_2}>\frac{nR}{P_1}

or    P_1>P_2

Correct option is 3.


Option 1)

Cannot be predicted

Incorrect

Option 2)

P2 = P1

Incorrect

Option 3)

P2 > P1

Correct

Option 4)

P2 < P1

Incorrect
