"' Carnot's theorem "'is a formal statement of this fact : " No engine operating between two heat reservoirs can be more efficient than a Carnot engine operating between those same reservoirs ."
22.
In addition to being an inexpensive material with a small resource cost, adobe can serve as a significant heat reservoir due to the thermal properties inherent in the massive walls typical in adobe construction.
23.
The immense depth of Crater Lake acts as a heat reservoir that absorbs and traps sunlight, maintaining the lake temperature at an average of on the surface and at the bottom throughout the year.
24.
Two of them are called heat reservoirs, so large that their respective non-deformation variables are not changed by transfer of energy as heat through a wall permeable only to heat to the working body.
25.
The total electric current density J multiplied by the voltage drop across the circuit, F _ e, and the system volume V, divided by the absolute temperature T, of the heat reservoir times Boltzmann's constant.
26.
He also uses the phrase " thermal equilibrium " while discussing transfer of energy as heat between a body and a heat reservoir in its surroundings, though not explicitly defining a special term'thermal equilibrium '.
27.
To boost the " renewables " ratio, geothermal power is often counted as renewable, even though the geothermal heat reservoirs are depleted ( observably so at Wairakei, the longest-running ), and, they are not emissions-free.
28.
If the entire body is treated as lumped capacitance heat reservoir, with total heat content which is proportional to simple total heat capacity C, and T, the temperature of the body, or Q = C T.
29.
Then, by externally forcing ideally slowly the separating membranes together, back to contiguity, work is done on the mixed gases, fictively reversibly separating them again, so that heat is returned to the heat reservoir at constant temperature.
30.
In the Carnot cycle there is strict necessity that the working fluid be at the same temperatures as the heat reservoirs they are in contact with and that they are separated by adiabatic transformations which prevent thermal contact.
