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.
Zvimwe zvinobvunzwa zvakanyanya
Chii chinonzi ideal gas law?
PV = nRT inobatanidza mhepo, huwandu, moles uye tembiricha yeakanaka gasi kuburikidza neyakajairika R = 8.314 J/(mol·K).Rearrange kuti uwane mhinduro yeimwe chete yezvikonzero.
Ndezvipi zviyero zvakarurama?
Mumidziyo yose, zvinhu zvese zvinoitwa muSI — pascals, cubic metres, moles uye kelvin — neR = 8.314. Mole imwe yegasi pa0 °C (273.15 K) ne1 atm inotora 22.4 L (0.0224 m³). Dzvanya chero imwe michina yaunoda; calculator ichashandura ichikushandura iwe.
Nei tembiricha inofanira kunge iri muKelvin?
PV = nRT inoshandisa tembiricha yakazara, uko 0 K ndiyo zero yakazara. Celsius neFahrenheit ine zeros yakaipa, saka kubatanidza °C zvinopa mhinduro dzakaipa. Ziva 273.15 ku °C kuti uwane kelvin — calculator inoita izvi otomatiki.
Chii chinonzi STP uye molar volume?
Standard tembiricha uye pressure inowanzova 0 °C uye 1 atm, apo imwe mole yeakanaka gasi inotora pamusoro pe22.4 malitha. Iyi "molar volume" ndiyo yakapusa cheki: kana yako mhinduro yeimwe mole yakati wandei iri kure kubva pa22.4 L, tarisazve mayuniti.
Panguva ipi iyo yakakwana gasi mitemo inoparadzwa?
Inonyanya kunyatsoshanda pamamiriro ekunze akaomarara, asi inowanzoita kuti zvive zvakaoma kunyatsoshanda pamamiriro ekunze akaomarara, semuenzaniso, pamamiriro ekunze akaomarara, apo mvura inopisa inopisa uye inopisa, kana kupisa kwakanyanya, uko mvura inopisa inopisa.
Sei kuchinja imwe variable kunogona kukonzera kuti vamwe vaite sei?
Pazviyo zvakamira, mhepo uye mvura zvinodarika zvakaenzana (Boyle’s law), asi mhepo nemvura dzinodarika zvakaenzana (Charles’s law). Kana ukapisa chisimbiso chinorema, mhepo inowedzera zvichienderana nesimba remvura. Kana ukapisa chisimbiso chinorema, mhepo inowedzera zvichienderana nesimba remvura.
Chii chiyero cheR ndinofanira kushandisa?
Izvi zvinobva pazvikwata. MuSI icho chinonzi 8.314 J/(mol·K); muliter-atmospheres icho chinonzi 0.08206 L·atm/(mol·K). Iyi calculator inoita basa muSI mukati mechikwata neR = 8.314, saka unogona kuisa chero chikwata uye chinozviwirirana.
