Constant volume process
Understanding the Isochoric Process
In thermodynamics, a process refers to a change in the state of a system from an initial state to a final state. These processes can occur under different conditions, such as keeping one of the properties constant.
The question asks for another name for the isochoric process.
An isochoric process is a thermodynamic process in which the volume of the closed system undergoing the process remains constant (isochoric comes from Greek "iso" meaning equal and "choric" meaning space or volume). Because the volume does not change, no work is done on or by the system due to expansion or compression.
Let's look at the options provided:
- Constant volume process: This definition perfectly matches the description of an isochoric process, where the volume (V) remains constant (\(V = \text{constant}\)).
- Constant temperature process: This is known as an isothermal process (\(T = \text{constant}\)).
- Constant pressure process: This is known as an isobaric process (\(P = \text{constant}\)).
- Constant enthalpy process: This is known as an isenthalpic process (\(H = \text{constant}\)), often seen in throttling processes.
Therefore, the isochoric process is also known as a constant volume process.
