A cyclic process 1-2-3-4-1 is depicted on $V-T$ diagram. The $p-V$ diagram and $p-V$ diagrams for this cyclic process are given below. Select the incorrect choices. 

Process 1-2 $V=$constant$, p\propto T$

$T$ is increasing. Therefore, pressure will increase.

Process 2-3 $p=$constant$, V\propto T$

$V$ and $T$ both are increasing

Process 3-4 $T=$constant$, p\propto \frac{1}{V}$

$V$ is increasing. Therefore, $p$ will decrease.

Process 4-1 inverses of process 2-3
