Thermodynamic functions - Phase Transformations Group
... The heat capacity can be determined experimentally using calorimetry. The data can then be related directly to the functions of state H, G and S. The heat capacity varies with temperature and other factors and hence is important in determining the stabilities of phase. It is useful to factorise the ...

... 0th Law of thermodynamics: There exists a useful scalar quantity called temperature that is a property of all thermodynamics systems. When 2 bodies (A and B) are in thermal equilibrium (same temperature) with a third body (C), then all bodies (AC, BC, AB) are in equilibrium with each other. 1st Law ...

Heat Transfer Oil
... In many industrial applications heating is provided indirectly by circulating hot oil through a heat exchanger, thus reducing hot spots and increasing the safety of the heating process. In quenching applications, heat is required to be rapidly drawn away from the parts in contact with the oil. Due t ...

Joule-Thomson Expansion
... So what can we conclude? Several things. First, since µ JT is positive at low temperatures and negative at high temperatures, it must have an inversion temperature. Second, the effect seems to depend (as we expected) on the attractive and repulsive forces acting between molecules. At low temperature ...
