WebA polytropic process is any thermodynamic process that can be expressed by the following equation: pV n = constant. The polytropic process can describe gas expansion and compression, which include heat transfer.The exponent n is known as the polytropic index, and it may take on any value from 0 to ∞, depending on the particular process. WebConclusions. Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases …
