Then, a thermometer was set up behind the plug to note any changes and generally cooling was observed.
Its namesake coefficient, mu, is defined as the rate of change of temperature T with pressure p. To verify it, an apparatus that pumped air uniformly through a long tube was set up. At a location protected against heat conduction, the tube was plugged with compressed wool. Then, a thermometer was set up behind the plug to note any changes and generally cooling was observed. FTP, name this effect whereby a temperature change occurs upon adiabatic expansion of a gas.
