WebCalculating specific internal energy is simple and straightforward. It is represented by the symbol Es, and it follows the following formula: Es = TE / TM Where Es is the specific internal energy (J/kg), TE is the total internal energy (Joules), and TM is the total mass (kg) of the substance. WebEnthalpy is a thermodynamics property of a substance and is defined as the sum of its internal energy and the product of its pressure and volume. H = U + PV. Specific Heat (c) Experiment shows that the temperature rise of liquid water due to heat transfer to the water is given by. Q = m c (T 2 - T 1) where.
