Adolfo Bartoli (19 March 1851 – 18 July 1896) was an Italian physicist, who is best known for introducing the concept of radiation pressure from thermodynamical considerations. Born in Florence , Bartoli studied physics and mathematics at the University of Pisa until 1874.
The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as ...
At that time, cannons were cast at the foundry with an extra section of metal forward of what would become the muzzle, and this section was removed and discarded later in the manufacturing process. [ 12 ] [ g ] Rumford took an unfinished cannon and modified this section to allow it to be enclosed by a watertight box while a blunted boring tool ...
German physicist and mathematician Rudolf Clausius restated Carnot's principle known as the Carnot cycle and gave to the theory of heat a truer and sounder basis. His most important paper, "On the Moving Force of Heat", [3] published in 1850, first stated the second law of thermodynamics. In 1865 he introduced the concept of entropy.
The flow of heat is a form of energy transfer. Heat transfer is the natural process of moving energy to or from a system, other than by work or the transfer of matter. In a diathermal system, the internal energy can only be changed by the transfer of energy as heat: =.
the process of heat or phonon emission by charge carriers in a solar cell, after a photon that exceeds the semiconductor band gap energy is absorbed. [ 3 ] The hypothesis, foundational to most introductory textbooks treating quantum statistical mechanics , [ 4 ] assumes that systems go to thermal equilibrium (thermalisation).
1665 – Robert Hooke published his book Micrographia, which contained the statement: "Heat being nothing else but a very brisk and vehement agitation of the parts of a body." [3] [4] 1667 – J. J. Becher puts forward a theory of combustion involving combustible earth in his book Physica subterranea [5] (see Phlogiston theory).
If, in a process of change of state of a closed system, the energy transfer is not under a practically zero temperature gradient, practically frictionless, and with nearly balanced forces, then the process is irreversible. Then the heat and work transfers may be difficult to calculate with high accuracy, although the simple equations for ...
