An ideal gas is taken from point $A$ to the point $B,$ as shown in the $P-V$ diagram. The work done in the process is

$A$ $P-T$ graph is shown for a cyclic process. Select the correct statement regarding this.

What is the nature of the change in internal energy for the following three thermodynamic processes shown in the figure?

$A$ thermodynamic process is shown in the figure. The pressure and volume at the points shown in the figure are as follows:
$P_A = 3 \times 10^{4} \text{ Pa}, V_A = 2 \times 10^{-3} \text{ m}^3, P_B = 8 \times 10^{4} \text{ Pa}, V_D = 5 \times 10^{-3} \text{ m}^3.$
In process $AB$, $600 \text{ J}$ of heat is added to the system, and in process $BC$, $200 \text{ J}$ of heat is added. The change in internal energy during the process $AC$ is: (in $\text{ J}$)

In the following $p-V$ diagram, the equation of state along the curved path is given by $(V-2)^2 = 4aP$, where $a$ is a constant. The total work done in the closed path is:

The heat energy absorbed by a system in going through a cyclic process shown in the figure is:
