An isochoric process is a thermodynamic process, in which the volume of the closed system remains constant (V = const). ... For an ideal gas and a polytropic process, the case n ➝ ∞ corresponds to an isochoric (constant-volume) process. See also: What is an Ideal Gas. Let assume an isochoric heat addition in an ideal gas.

Is an isobaric process polytropic?

1 Polytropic Process. where v = 1 / ρ is the specific volume, n is the polytropic index, and C is a constant. The condition of represents an isobaric process, represents an isothermal process, n = γ = c p / c v represents an isentropic process, and represents an isochoric process.

Which processes are polytropic?

The term "polytropic" was originally coined to describe any reversible process on any open or closed system of gas or vapor which involves both heat and work transfer, such that a specified combination of properties were maintained constant throughout the process.
