− | An isothermal process is a change of a system, in which the temperature remains constant. In this diagram the volume increases (expansion) or decreases (compression). The term isentropic describes a lossless process where no heat leaves the gas, here the increased volume only causes a further decrease in pressure; it is also called | + | An isothermal process is a change of a system, in which the temperature remains constant. In this diagram the volume increases (expansion) or decreases (compression). The term isentropic describes a lossless process where no heat leaves the gas, here the increased volume only causes a further decrease in pressure; it is also called adiabatic process and is the thing which warms air when you compress it quickly. Isentropic means "doesn't cause the heat death of the universe.", which is a rare thing. |
The prefix ''iso-'' is derived from the Ancient Greek word ''ísos'' which translates to ''equal'' and used widely in modern days in science like here to indicate a process at the same temperature (-thermal) which is not shown in the graph. The prefix ''is-'' to the term {{w|Entropy|entropy}} is used because isoentropic sounds stupid. | The prefix ''iso-'' is derived from the Ancient Greek word ''ísos'' which translates to ''equal'' and used widely in modern days in science like here to indicate a process at the same temperature (-thermal) which is not shown in the graph.
