When a system is taken from state $a$ to state $b$ along the path $acb$, it is found that a quantity of heat, $Q=200 \mathrm{J}$ is absorbed by the system and work, $W=80 \mathrm{J}$ is done by it. Along the path $adb$,$Q=144 \mathrm{J}$.

If $U_{\mathrm{a}}=40 \mathrm{J}$, the value of $U_{\mathrm{b}}$ will be,

When a system is taken from state $a$ to state $b$ along the path $acb$, it is found that a quantity of heat, $Q=200 \mathrm{J}$ is absorbed by the system and a work, $W=80 \mathrm{J}$ is done by it. Along the path $adb$,$Q=144 \mathrm{J}$. Internal energy at $a$ is $U_a=40 \mathrm{J}$

If $U_d = 88 \mathrm{J}$, heat absorbed for the path $‘\mathrm{db}’$ is

Ideal gas is taken through the process shown in figure:

If molar heat capacity of the given process (as shown in figure) is $C$, then,
