Utatatua PV = RT kwa mabadiliko yoyote, kwa uchaguzi wako wa msongo, kiasi na halijoto.
Matokeo yanakuwa bora zaidi unapochapa.
Kuhusu kifaa hiki cha kupigia hesabu
The ideal gas law ties together the four state variables of a gas in one equation, PV = nRT: pressure times volume equals the number of moles times the gas constant times the absolute temperature. The constant R = 8.314462618 J/(mol·K) in SI units. Rearranged, you can solve for any variable — P = nRT/V, V = nRT/P, n = PV/RT or T = PV/nR — and this calculator does exactly that, converting pressure (Pa, kPa, bar, atm, mmHg, psi), volume (m³, L, mL, cm³) and temperature (K, °C, °F) internally so you can work in whatever units you have.
The classic worked example is one mole of gas at standard temperature and pressure: at 0 °C (273.15 K) and 1 atm, V = nRT/P = 1 × 8.314 × 273.15 / 101,325 ≈ 0.0224 m³, or the familiar 22.4 litres per mole. Heat that gas to 300 K at constant pressure and the volume rises in proportion, since V ∝ T. A crucial detail: temperature must be absolute — always convert °C or °F to kelvin (add 273.15 to °C) before the math, which the calculator handles for you.
The law is called "ideal" because it assumes gas molecules have no volume and do not attract one another. Real gases follow it closely at ordinary pressures and temperatures well above their boiling point, and it is the everyday tool for scuba and diving gas calculations, chemistry stoichiometry of gases, HVAC and pneumatics, and estimating how a balloon or tyre responds to heating and cooling. It becomes less accurate at very high pressure or near condensation, where equations like van der Waals do better.
Maswali yaliyoulizwa mara nyingi
Ni nini iliyo sheria bora ya gesi?
PV = RCT huunganisha shinikizo, ukubwa, mikoko na halijoto ya gesi bora kupitia R = 8.314 J/Gother·K).
Ni nini vipimo sahihi?
Ndani ya kila kitu kuna SI pascals, disketi za mraba, fuko na kelvin Évin Équine na R = 8.314. Mko mmoja wa gesi kwenye 0 °C (273.15 K) na 1 saa za mkononi zinachukua karibu 22.4 L (0.0224 m3).
Kwa nini ni lazima halijoto iwe katika shekeli?
PV = RT hutumia halijoto kamili, ambapo 0 K ni sufuri kamili. Sasira na sufuri zina sufuri zisizo na mpangilio, kwa hiyo kuunganishwa katika °C hutoa majibu yasiyo sahihi. Oongeza 273.15 ili kupata kelvin Éton Étells hufanya hivyo kwa njia ya moja kwa moja.
ESTP na dialar ni nini?
Kiwango cha joto na shinikizo kwa kawaida ni 0 °C na 1 asubuhi, ambapo fuko mmoja wa gesi inayofaa huwa na viwasha - moto vya karibu 22.4.
Sheria inayofaa ya gesi huvunjwa wakati gani?
Ni sahihi sana katika msongo wa kiasi na halijoto kuliko kiwango cha kuchemsha, lakini hukua kuwa si sahihi wakati wa msongo wa juu au karibu na uchanganyaji, ambapo ukubwa wa molekuli na mata yenye kuvutia.
Kubadilisha moja kwatofautiana kunaathirije wengine?
Katika fuko zisizobadilika, msongo na ukubwa wa vitu vinahusiana kwa werevu (sheria yaBoyle Mitume), ilhali kiasi na halijoto kamili zahusiana moja kwa moja (sheria ya Kharlestokas).
Nitumie thamani gani ya R?
It depends on units. In SI it is 8.314 J/(mol·K); in litre-atmospheres it is 0.08206 L·atm/(mol·K). This calculator works in SI internally with R = 8.314, so you can enter any units and it reconciles them.
API bustanini hutumia kifaa hiki cha hesabu kutoka kwenye mfumo wa sheria
Ipigie simu kifaa hiki cha kupigia hesabu kama Junse É not doot toder. Chochote unachoacha kinatumia kiwango kilekile cha mwisho ambacho ukurasa huu haujakamilika; parameta isiyojulikana ni 400, si sufuri kimya kamwe. Soma habari kamili za API docs →
