Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die ideale gaswet?
PV = NRT verbind druk, volume, mole en temperatuur van'n ideale gas deur die konstante R = 8,314 J/edol·K). herwissel dit om op te los vir enige enkele veranderlike.
Wat is die regte eenhede?
Internally everything is SI — pascals, cubic metres, moles and kelvin — with R = 8.314. One mole of gas at 0 °C (273.15 K) and 1 atm occupies about 22.4 L (0.0224 m³). Enter any units you like; the calculator converts for you.
Waarom moet temperatuur in kelvin wees?
PV = nRT gebruik absolute temperatuur, waar 0 K absolute nulle is. Celsius en Fahrenheit het arbitrêre nulle, sodat propering in °C direk verkeerde antwoorde gee. Voeg by 273.15 tot °C om kelvin ium die sakrekenaars dit outomaties te kry.
Wat is STP en molar - volume?
Standaard temperatuur en druk is gewoonlik 0 °C en 1 atm, waar een mol van 'n ideale gas beslaan omtrent 22,4 litre. Hierdie "molar volume" is 'n nuttige tjek: as jy die gevolg vir een mol naby daardie voorwaardes is ver van 22,4 L, herkies die eenhede.
Wanneer verbrokkel die ideale gaswet?
Dit is baie akkuraat teen matige druk en temperature wat ver bo die kookpunt is, maar groei onakkurate by hoë druk of naby kondensasie, waar molekulêre volume en aantreklikhede saak. Real-gas vergelykings hou van der Atomic element hanteer dit.
Watter uitwerking het die veranderende een veranderlike op die ander?
By vaste moesies word druk en volume op inverse wyse verbind (Byle noudat die wet van die manlike wet oor die bors en absolute temperatuur direk verwant is (Charlesviks - wet).'n Digte houer word met die druk in verhouding tot die kelvintemperatuur verseël.
Watter waarde van R moet ek gebruik?
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.
