The sum of all possible kinds of energies of all atoms, molecules or ions within a system is called:
Correct answer: B. Internal energy
- A. Test
- B. Internal energy
- C. Potential energy
- D. Bond energy
Explanation
Internal energy refers to the total energy of all the atoms, molecules, or ions within a system. It includes different types of energy, like kinetic energy (energy of motion) and potential energy (energy stored in bonds or positions). The internal energy of a system can change due to factors like heat transfer or work done on the system. It's an important concept in thermodynamics to understand the energy state of a system.

About Internal Energy
Internal energy is the total microscopic kinetic and potential energy of a system and is a state function. The first law, ΔU = q + w, connects changes in internal energy with heat and work, including sign conventions, expansion or compression and constant-volume processes.
