As we have learned

Equation of state for isochoric process & indicator diagram -

- wherein

in P-V diagram line is parallel to pressure line.

 

 Volume is constant so it is a isochoric process 

PV = RT   =>  P \propto T 

as P is increasing so T is also increasing 

\Delta Q = \Delta U + \Delta W \Rightarrow \Delta W = 0 \\\\ so \Delta Q = \Delta U 

As T is increasing so both \Delta Q \: \: and\: \: \Delta U  is positive
