Two of the architects of modem thermodynamics were William Thompson (better known as Lord Kelvin) and his friend James Prescott Joule - a scientist of great vision, and a master of accurate thermodynamic measurement, as well as being something of an English eccentric. For example, while on a holiday in Switzerland in 1847, Thompson met Joule. Let Thompson describe what he saw ... 

When an enzyme-catalyzed biochemical reaction operating in an isothermal system is in a non-equilibrium steady state, energy is continuously dissipated in the form of heat. The quantity J AG is the rate of heat dissipation per unit time. The inequality of Equation (4.13) means that the enzyme can extract energy from the system and dissipate heat and that an enzyme cannot convert heat into chemical energy. This fact is a statement of the second law of thermodynamics, articulated by William Thompson (who was later given the honorific title Lord Kelvin), which states that with only a single temperature bath T, one may convert chemical work to heat, but not vice versa. 

Lord Kelvin (1824-1907) was born William Thompson. At the age of ten he was admitted to Glasgow University. Because its new appliance was based on Kelvin s theories, a refrigerator company named its product the Kelvinator. 

The MRE effect, peculiar to MRE films such as Ni-Fe, was discovered by William Thompson and Lord Kelvin in 1856. Fig. 7.10.2 shows the principle of the MRE sensor. 

The onset of the hysteresis loop indicates the start of the capillary condensation mechanism. The desorption curve (AB C) is always above the adsorption branch (ABC), that is for a given loading adsorbate desorbs from a porous solid at a lower pressure than that required for adsorption. Before proceeding with the analysis of the isotherm, we first start with the basic capillary condensation theory of Lord Kelvin, the former William Thompson.

One of the early triumphs of the study of thermodynamics was the demonstration that there is an absolute zero of temperature. However, there are several different temperature scales, for historical reasons. All you need to know about this is that the kelvin scale (named after William Thompson, Lord Kelvin) has an absolute zero of OK and a temperature of 273.16K at the triple point where water, ice, and water vapor are at equilibrium together. The melting point of ice at one atmosphere pressure is 0.01 degrees less than this, at 273.15 K (Figure 3.1). The Celsius scale (named after Anders Celsius, a Swedish astronomer) has a temperature of 0 °C at the ice point (273.15 K) and absolute zero at -273.15°C. This gives almost exactly 100 C between the freezing and boiling points of water at one atmosphere, so water boils at 100 "C (373.15 K). Thus the numerical conversion between the two scales is... 

William Thompson, Lord Kelvin (1824-1907). Scottish mathematician and physicist. Kelvin did important work in many branches of physics. 

James Prescott Joule measured the increase in temperature when rubber was stretched in 1859. William Thompson (Lord Kelvin) was one of the few natural philosophers (scientists) to recognize the importance of Joule s investigations. He developed an equation for quantifying Joule s discovery in 1857. Units for temperature and energy have been named after these polymer pioneers.
