As such the energy balance is also an essential tool used to check data accuracy, as large statistical differences in energy units, apparent energy gains or large losses in transformation processes, or large unexplained variations in shares or in high-level indicators may all indicate underlying data problems.

### Mass And Energy Balances

Mass and Energy Balances. One of the fundamental laws of physics states that mass can neither be produced nor destroyed---that is, mass is conserved. Equally fundamental is the law of conservation of energy. Although energy can change in form, it can not be created or destroyed.

The energy content of a control volume changes with time during an unsteady-flow process. The magnitude of change depends on the amount of energy transfer across the system boundaries as heat and work as well as on the amount of energy transported into and out of the control volume by mass during the process.
