Physics zer the work for which it was designed. This means that there is no heat engine whose income is 100%. The law of conservation of energy would be wrong? To share ideas, Carnot began the groundwork for that establish what would later be called the "2nd Law of Thermodynamics." Furthermore, it was able to realize that the motive power of the caloric exclusively dependent on the temperature of hot and cold sources. Wanting to get a more efficient machine, idealized a Carnot heat engine whose income would be the greatest of all. This machine would use no more water vapor, like Watt, but another gas. How would this be achieved? Through his studies, he was able to realize maximum efficiency would be achieved only when the change in temperature of the gas in the cylinder, whichis the piston, was caused by the variation of the volume of this gas. This would occur when there is no contact between the hot and cold sources of the machine. However, how to achieve volume change (contraction and dilation of the gas) without contact between the hot and cold sources? Because that is where the machine devised by Carnot. How could we better visualize this machine? One way would be represented by a diagram of the operation of the machine. Another way would be through a chart or graph, representing the complete cycle of the Carnot engine, but this is for you. SEARCH How about a search for books, journals and even on the Internet about the Carnot engine. Draw a schematic of the operation of the machine and also its representation through a graph. Thermal transformations that occur during machine operation. On the machine devised by Carnot, there is no contact between the hot source and cold source. What kind of physical process occurs? Seek to answer the following question: is it possible to use the Carnot engine in a real situation? The graphical representation of the theoretical Carnot cycle and its operation was done by Émile Clapeyron(1799-1864). Scientist This algebraic formulation also incorporates the work of Carnot. The procedure adopted by Clapeyron gives greater clarity to the work of Carnot, are of fundamental importance for the study of thermodynamics. At this time, many researchers have related the heat to other forms of energy (conversion of kinetic energy into heat through friction and release of energy in chemical reactions), there Steam and Movement

Fizika zer posao za koji je namijenjen. To znači da nema topline motora čiji prihod je 100%. Zakon očuvanja energije će biti u krivu? Za razmjenu ideja, Carnot je počeo temelje za koje se utvrdi što će se kasnije nazvati "drugi zakon termodinamike." Nadalje, to je bio u mogućnosti shvatiti da je motiv moć kalorija ovisi isključivo o temperaturi toplih i hladnih izvora. U želji da se učinkovitije stroj, idealiziran je Carnot toplinski motor čiji prihod će biti najveći od svih. Ovaj stroj će koristiti ne više vodene pare, kao što je Watt, ali drugi plin. Kako bi se to može postići? Kroz studija, on je bio u mogućnosti da ostvari maksimalna učinkovitost će se postići samo kada je promjena u temperaturi plina u cilindru, gdje jeklip, bio uzrokovan promjenom obujma tog plina. To će se dogoditi kada nema kontakta između toplih i hladnih izvora stroja. Međutim, kako bi se postigla promjena volumena (kontrakcija i dilatacija od plina) bez kontakta između toplih i hladnih izvora? Budući da je mjesto gdje je stroj montiran od Carnot. Kako bi se bolje vizualizirati ovaj stroj? Jedan način bi se zastupa dijagram rada stroja. Drugi način bi se kroz grafikon ili graf, predstavlja cjelovit ciklus Carnot motor, ali ovo je za tebe. TRAŽI Kako o potrazi za knjigama, časopisima, pa čak i na internetu o Carnot motor. Nacrtaj shematski u radu stroja i njegova zastupljenost kroz graf. Toplinski transformacijama koje se odvijaju tijekom rada uređaja. Na stroju osmislio Carnot, nema kontakta između tople i hladne izvor izvor. Kakav fizičkog procesa događa? Tražite odgovoriti na sljedeće pitanje: je li moguće koristiti Carnot motor u realnoj situaciji? Grafički prikaz teorijskih Carnotove a njegov rad je učinio Émile Clapeyronova(1799-1864). Znanstvenik Ova algebarska formula također uključuje rad Carnot. Postupak usvojila Clapeyronova daje veću jasnoću u radu Carnot, od temeljne važnosti za proučavanje termodinamike. U ovom trenutku, mnogi znanstvenici su prenosili topline na druge oblike energije (pretvorba kinetičke energije u toplinu zbog trenja i oslobađanje energije u kemijske reakcije), postoji Para i pokret99
