dU_c = dH-(p*dV_small)
This formula uses 4 Variables

Variables Used

Change in Internal Energy of the System - (Measured in Joule) - Change in Internal Energy of the System is defined as all the energy within a given system, including the kinetic energy of molecules and the energy stored in all of the chemical bonds .
Change in Enthalpy in the System - (Measured in Joule) - Change in Enthalpy in the System is the thermodynamic quantity equivalent to the total difference between the heat content of a system.
Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Small Volume Change - (Measured in Cubic Meter) - Small Volume Change is the indicator that shows whether or not a volume trend is developing in either an up or down direction.

STEP 1: Convert Input(s) to Base Unit

Change in Enthalpy in the System: 2000 Joule --> 2000 Joule No Conversion Required
Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Small Volume Change: 0.2 Cubic Meter --> 0.2 Cubic Meter No Conversion Required
