Explanation:
According to the graph, P is directly proportional to T.
Applying the equation of state, we get,
PV = nRT
$=\frac{\text{nR}}{\text{V}}\text{T}$
Given: $\text{P}\propto\text{T}$
This means $\frac{\text{nR}}{\text{V}}$ is a constant. So, V is also a constant.
Constant V implies the process is isochoric.
