What will be the internal energy of a system at constant volume?
Correct answer: D. delta E = qv
- A. delta E =0
- B. delta E = q+p
- C. delta E = q+ PdeltaV
- D. delta E = qv
Explanation
The equation ΔE=QV relates the change in internal energy (ΔE) of a system at constant volume to the heat added or removed from the system (QV )

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
