Vocabulary of Thermodynamics
... When viewed perpendicular to the pressure and temperature axes, the two-phase regions are shown in edge view as lines separating the single-phase regions (labeled solid, liquid and vapor). The triple line is now shown in end view as a point. The second figure shows the P-v-T surface viewed perpendic ...

The Scope of Thermodynamics - Dicky Dermawan
... Thermodynamic State and State Function State functions are quantities which depend only on present conditions, however reached. State functions can be expressed mathematically as functions of thermodynamic coordinates such as temperature & pressure, their value can always be identified with points ...

Some ideas from thermodynamics
... from the source and insulated so no heat can flow in or out. The piston is further expanded, doing more work and allowing the temperature to fall to T2 . The cylinder is then placed in contact with the sink and the gas compressed so that heat flows into the sink. (Work has to be put in in order to c ...

... This range usually includes RT. From the figure it is seen that Cv is equal to 3R at high temperatures regardless of the substance. This fact is known as Dulong-Petit law. This law states that specific heat of a given number of atoms of any solid is independent of temperature and is the same for all ...

... temperature. All we have is a vague notion of “hot” and “cold,” and the observation that “heat” (whatever that is), always flows from a “hot” object to a “cold” one. To quantify this notion of “hot” or “cold,” we would like to assign a number that measures the “hotness” or “coldness” of an object, a ...
