| 11. | These parameters all affect the internal energy of a thermodynamic system.
|
| 12. | The internal energy of the gas remains the same, while the volume increases.
|
| 13. | Therefore, a convenient null reference point may be chosen for the internal energy.
|
| 14. | The manner by which a system achieves its internal energy is path independent.
|
| 15. | Internal energy is identifiable, it is a particular form of energy.
|
| 16. | It converts elecrical energy to internal energy, thus transfered as heat.
|
| 17. | :That depends on what you mean by " Internal energy ".
|
| 18. | :: Note that enthalpy is equal to internal energy + pressure * volume.
|
| 19. | In convection, internal energy is carried between bodies by a moving material carrier.
|
| 20. | In 1882 it was named as the " internal energy " by Helmholtz.
