An ideal gas is heated at constant pressure and absorbs$\text{'}Q\text{'}$ amount of heat. If the ratio $\frac{C_p}{C_v}=\gamma ,$ then

Figure shows $P~T$ diagram for $2$ moles of an ideal gas. The volume of the gas is nearly

The $P~V$ curve for $1$ mole of an ideal monoatomic gas during process $A\to B$ is shown in figure. The change in internal energy of the gas is

In the process shown by the graph the change in internal energy is $\Delta U,$ work done by the gas is $W$ and heat absorbed by the gas is $Q.$ Select the correct alternatives.
