School The volume of a gas is inversely proportional to the pressure,keeping the same temperature. Edmé Mariotte(1620-1684), French physicist and priest, after a few years, also studying gases, reached the same conclusion that Boyle is for this reason that the statement above is known as LawBoyle today. The chemistGay-Lussac (1778 - 1850) in 1801, as well as French and Amotons Mariotte noted, as Amontons had already done, that the gas changes its pressure due to its temperature when the volume is kept constant . You may be wondering, but that's not what Boyle and Mariotte said? And to be the reason, but there is a difference: in the case of Amontons andGay-Lussac, the pressure is that it was kept constant. Graphically we can represent as follows: Note that the extrapolation of the curve when the temperature is absolute zero Kelvin's own. This extrapolation confirmed at the time, which Amontons thought: "there should be a minimum temperature where the gases would have its pressure and volume reduced to zero." Calculating this temperature Amontons reached a value very close to the absolute temperature in Kelvin scale of-239.5 ° C. (Adapted from Medeiros, 1999) There is indeed the possibility that the volume of a quantity of gas is reduced to zero? And negative volume can exist? How can I make an extrapolation? If we have a graph that is a straight line inclined, as the graph on the left, this is possible. A similar function is described by equation (Y = ax + b), where the coefficient is the slope of the straight line (tangent of the angle formed by the straight line and the horizontal axis) and the coefficient is the point where the line crosses the vertical axis. Then, to determine the equation of the line, we need to and We will use the values of the adjacent chart to discover their function (formula). At the point i have a set of values (3.8), and the point ho set (2.5). In the function y = ax + b represented by the following graph, where V is Y and X is T, we have: 8a + b 3 = 2 + b = 5a Thermodynamics

Škola Volumen plina je obrnuto proporcionalna tlaku,imajući istu temperaturu. Edmé Mariotte(1620-1684), francuski fizičar i svećenik, nakon nekoliko godina, također studira plinove, doći do istog zaključka da je Boyle je iz tog razloga da se izjava gore je poznat kaoBoylea Zakonu danas. KemičarGay-Lussac (1778 - 1850) u 1801, kao i francuski i Amotons Mariotte navedeno, kao Amontons već učinjeno, da se plin mijenja pritisak zbog temperature kada volumen ostaje konstantna . Vi svibanj se pitate, ali to nije ono što Boyle i Mariotte rekao? I biti razlog, ali postoji razlika: u slučaju Amontons iGay-Lussac, pritisak je da je zadržao stalna. Grafički možemo predstavljati kako slijedi: Imajte na umu da ekstrapolacija krivulje kada je temperatura apsolutne nule Kelvin vlastiti. Ova ekstrapolacija potvrđeno i na vrijeme, što Amontons pomislio: "ne bi trebalo biti minimalna temperatura gdje se plinovi će imati svoj pritisak i volumen smanjuje na nulu." Izračun toj temperaturi Amontons dostigao vrijednost vrlo blizu apsolutne temperature u Kelvin skali od-239,5 ° C. (Preuzeto iz Medeiros, 1999) Tu je doista postoji mogućnost da se volumen količine plina je svedena na nulu? I negativni volumen može postojati? Kako mogu napraviti ekstrapolacija? Ako imamo graf koja je ravna crta skloni, kao graf na lijevoj strani, to je moguće. Slična funkcija opisuje jednadžba (Y = ax + b), gdjeje koeficijent je nagib pravca (tangens ugla formira ravnu liniju i horizontalne osi) i koeficijentB je točka u kojoj pravac siječe okomitu os. Zatim, odrediti jednadžbu pravca,trebamo Mi ćemo koristiti vrijednosti susjedne grafikonu otkriti svoju funkciju (formula). U trenutku imam set vrijednosti (3,8), a set point ho (2,5). U funkciji y = ax + b predstavljen sljedećom grafu, gdje V je Y i X je T, imamo: 8a + b 3 = 2 + b = 5a Termodinamika
