Physics - Heat & Thermo Question with Solution | TestHub

In a process $AB$ at constant volume 500 J of heat is added. Then in an isobaric process $BC$ at $5\times 10^4$ Pa the volume rises from $1\times 10^{-3}$ $m^3$ to $4\times 10^{-3}$ $m^3$ and 350 J of heat is added. Find the change in internal energy from $A$ to $C$ in joules.
