Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Waa maxay sharciyada gaaska ugu fiican?
PV = nRT waxay isku xirtaa cadaadiska, miisaanka, moles iyo heerkulka gaaska caadiga ah iyadoo la adeegsanayo R = 8.314 J/(mol·K). Ku darso si aad u xalliso isbeddel kasta oo keliya.
Waa maxay unugyada saxda ah?
Gudaha wax walba waa SI — pascals, mitir cubic, moles iyo kelvin — R = 8.314. Mid ka mid ah moles gaaska at 0 ° C (273.15 K) iyo 1 atm qabsato ku saabsan 22.4 L (0.0224 m³).
Maxaa keena in heerkulku yahay kelvin?
PV = nRT wuxuu isticmaalaa heerkulka buuxa, halkaas oo 0 K waa zero buuxa. Celsius iyo Fahrenheit waxay leeyihiin zeros qalad ah, sidaas darteed ku xiran °C si toos ah u bixiyaan jawaabaha qalad ah. Ku dar 273.15 °C si aad u hesho kelvin — xisaabinta ayaa si otomaatig ah u sameeyaan.
Maxaa STP iyo miisaanka molar?
Heerkulka iyo cadaadiska caadiga ah waa 0 °C iyo 1 atm, oo ah mid ka mid ah gaaska caadiga ah ee ku yaal 22.4 litir. "Waajibka molar" waa tijaabo fudud: haddii natiijadaada mid ka mid ah moles ee xaaladahaas ku dhow ay ka fog tahay 22.4 L, dib u eegista unugyada.
Goorma ayaa sharciga gaaska caadiga ah la burburiyaa?
Waa mid aad u sax ah oo ku saabsan cadaadis dhexdhexaad ah iyo heerkulka sare ee heerkulka sare, laakiin wuxuu ku korayaa si aan sax ahayn heerkulka sare ama ku dhow isku darka, halkaas oo miisaanka molecular iyo xiisaha ay muhiim u yihiin.
Sidee u beddelidda mid ka mid ah isbeddelka saameyn ku leh kuwa kale?
Marka mols go'an, cadaadis iyo tirada waa la xiriira si ka duwan (Boyle ee sharciga), halka tirada iyo heerkulka buuxa waa la xiriira si toos ah (Charles ee sharciga). Ku karkari baakadaha adag oo la xidhay iyo cadaadisku wuxuu kor u kacayaa si la mid ah heerkulka kelvin.
Maxay tahay qiimaha R waa inaan isticmaalo?
Waxay ku xiran tahay unugyada. SI waa 8.314 J / (mol · K); in litir-atmospheres waa 0.08206 L · atm / (mol · K). Kalkulatorkan arbetar i SI internt med R = 8.314, så du kan ange några enheter och det stämmer dem.
