Bu hasapçy hakda
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.
Köp soralýan soraglar
Ideal gaz kanun näme?
PV = nRT basy, bolumy, mollary we ideal gazyň temperaturasyny R = 8.314 J/(mol·K) bilen baglanyşdyrýar. Her bir bir üýtgeýji üçin çözmek üçin ony täzeden düzeltmek
Sag birlik nädir?
Içinde her zady SI - paskal, kub metr, mol we kelvin - R = 8.314 bilen. Bir mol gaz 0 °C (273.15 K) we 1 atm 22.4 L (0.0224 m³) ýykgyn edyar. Isleýän birligini giriz; kalkulýator siziň üçin üýtgedýär.
Näme üçin temperatura kelwinde bolmaly?
PV = nRT absolute temperature uses, where 0 K is absolute zero. Celsius and Fahrenheit have arbitrary zeros, so plugging in °C directly gives wrong answers. Add 273.15 to °C to get kelvin - the calculator does this automatically.
STP we molar boluş näme?
Standart temperatura we basyş 0 °C we 1 atm, bir mol ideal gazyň 22.4 litr meýdanyny tutýan standart temperatura we basyş. Bu "molar göwrüm" bir amatly barlagdyr: eger siziň bir mol üçin netijeňiz şu şertlerde 22.4 L-den uzak bolsa, birlikleri ýene barlaň.
Ideal gaz kanuny näçe wagt bozulýar?
Bu ortaça basyşlar we gyzgynlyklarda gaty dogry, ýöne ýokary basyşlarda ýa-da molekular göwrüm we çekişlikleriň ähmiýetli bolandygy üçin, kondensasionyň golaýynda dogry däl. Van der Waals ýaly hakykat gaz deňlemeleri olary dolandyrýar.
Bir üýtgedijiň üýtgemegi beýlekileri nädip täsir eder?
Fixed mols, pressure and volume are reversely related (Boyle's law), while volume and absolute temperature are directly related (Charles's law). Heat a sealed rigid container and the pressure rises proportionally to the kelvin temperature.
R-niň näçelik bahasyny ulanmak gerek?
Bu birliklerden bagly. SI-de bu 8.314 J/(mol·K); litre-atmosferlerde bu 0.08206 L·atm/(mol·K). Bu kalkulýator SI-de R = 8.314 bilen işleýär, şonuň üçin siz islendik birligi girip olary deňleýärsiňiz.
