STEP 0: Pre-Calculation Summary

Formula Used

Temperature = (Internal Energy-Helmholtz Free Energy)/Entropy
T = (U-A)/S
This formula uses 4 Variables

Variables Used

Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Internal Energy - (Measured in Joule) - The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Helmholtz Free Energy - (Measured in Joule) - Helmholtz free energy is a thermodynamics concept in which, the thermodynamic potential is used to measure the work of a closed system.
Entropy - (Measured in Joule per Kelvin) - Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.

STEP 1: Convert Input(s) to Base Unit

Internal Energy: 1.21 Kilojoule --> 1210 Joule (Check conversion here)
