An isobaric process is a process, in which the pressure remains constant. An isochoric process is a process, in which the volume remains constant.

WebJan 15, 2024 · The work of a reversible expansion of an ideal gas is fairly easy to calculate. If the gas expands reversibly, the external pressure () can be replaced by a single value () which represents both the pressure of the gas and the external pressure. or But now that the external pressure is not constant, cannot be extracted from the integral. WebJun 16, 2024 · Isochoric Process. For a thermodynamics process, if the volume remains constant for a system, the process is known as an Isochoric process. For this process according to the first law of thermodynamics ΔQ = ΔW +ΔU, so if volume remains constant this means ΔV=0 hence ΔW = 0. ∴ ΔQ = ΔU. Hence in this process, the Heat supplied will …

WebJan 5, 2024 · The difference between the reversible and irreversible process is the change in entropy for the latter is composed of two components: entropy change = entropy transfer + entropy generated. For the former it is only entropy change = entropy transfer. WebApr 15, 2024 · 2.5.2 Isochoric process. As the name suggests, isochoric processes are carried out by keeping the volume constant. For an ideal gas, it is a vertical plane in the \(P-V-T\) space (Figure 1). Therefore, the work done for isochoric processes is zero. 2.5.3 Isobaric process.
