Internal Energy Sentence Examples

  • Now a well-known relation connects the available energy of a reversible system with the corresponding change in its total internal energy.

  • Since the final state of the system would be the same as in the actual processes of the cell, the same amount of heat must give a measure of the change in internal energy when the cell is in action.

  • Thus, if L denote the heat corresponding with the chemical changes associated with unit electric transfer, Le will be the heat corresponding with an electric transfer e, and will also be equal to the change in internal energy of the cell.

  • If l is the heat of dilution per unit change of volume in a calorimeter where all the energy goes to heat, the change in internal energy U is measured by ldv.

  • E.g. do we really know the initial holdup and internal energy in the tank?
