How to Evaluate Work using First Law of Thermodynamics?

Work using First Law of Thermodynamics evaluator uses Work done in Thermodynamic Process = Change in Internal Energy-Heat Transferred in Thermodynamic Process to evaluate the Work done in Thermodynamic Process, The Work using First Law of thermodynamics formula is defined as difference between internal energy and heat into system. in thermodynamics, work performed by a system is energy transferred by system to its surroundings, by a mechanism through which system can spontaneously exert macroscopic forces on its surroundings. in surroundings, through suitable passive linkages, work can lift a weight, for example. Energy can also transfer from surroundings to system; in a sign convention used in physics, such work has a negative magnitude. Work done in Thermodynamic Process is denoted by W symbol.

How to evaluate Work using First Law of Thermodynamics using this online evaluator? To use this online evaluator for Work using First Law of Thermodynamics, enter Change in Internal Energy (ΔU) & Heat Transferred in Thermodynamic Process (Q) and hit the calculate button.
