Typical processes for which a heat capacity may be defined include isochoric ( constant volume, \ text { d } V = 0 ) processes.
12.
Because it does not change the volume of the system it is not measured as pressure-volume work, and it is called isochoric work.
13.
Rudolf Diesel patented the compression-ignition engine in 1892; however his injection system, where combustion was produced isochoric combustion developed at Hornsbys being preferred.
14.
An example of isochoric work is when an outside agency, in the surrounds of the system, drives a frictional action on the surface of the system.
15.
For a simple system, mechanical isolation is equivalent to a state of constant volume and any process which occurs in such a simple system is said to be isochoric.
16.
The other extreme kind of work is isochoric work ( 0 } } ), for which energy is added as work solely through friction or viscous dissipation within the system.
17.
In the simplest cases, for example, there are work of change of volume against a resisting pressure, and work without change of volume, known as isochoric work.
18.
The thermometric body should be composed of a material that has a strictly monotonic relation between its chosen empirical thermometric variable and the amount of adiabatic isochoric work done on it.
19.
The isochoric heat capacity per particle of a monatomic liquid near to the melting line is close to 3 k _ B ( where k _ B is the Boltzmann constant ).
20.
The second law of thermodynamics observes that a natural process, of transfer of energy as work, always consists at least of isochoric work and often both of these extreme kinds of work.
