A process in which heat absorbed is 5J and work done by gas is 8J . What is internal energy |
| Answer» TION:Given that the work is done on the surrounding, i.e., the work is done by the system and the heat is absorbed by the system.Therefore,q=5kJw=8JNow from first law of THERMODYNAMICS,ΔU=q+w⇒ΔU=5+8=13JHence the CHANGE in internal energy is 13J | |
