How to Evaluate Adiabatic Expansion?

Adiabatic Expansion evaluator uses Work Done by the System = 8.314*(High Temperature-Low Temperature)/(Adiabatic Coefficient-1) to evaluate the Work Done by the System, The Adiabatic Expansion formula is defined as the expansion in which no heat is added or subtracted from the air, and the internal energy of the air is increased, which is equal to the external work done on the air. Work Done by the System is denoted by Wsys symbol.

How to evaluate Adiabatic Expansion using this online evaluator? To use this online evaluator for Adiabatic Expansion, enter High Temperature (Thigh), Low Temperature (Tlow) & Adiabatic Coefficient (γ) and hit the calculate button.
