וואָס איז דער אידיעלע גאַס־געזעץ?
PV = nRT links pressure, volume, moles and temperature of an ideal gas through the constant R = 8.314 J/(mol·K). Rearrange it to solve for any single variable.
וואָס זענען די רעכטע איינציקײטן?
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.
װאָס איז דער טעמפּעראַטור?
PV = nRT uses absolute temperature, 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.
וואָס איז STP און מאָלער פֿאָלק?
Standard temperature and pressure is commonly 0 °C and 1 atm, at which one mole of an ideal gas occupies about 22.4 litres. This "molar volume" is a handy check: if your result for one mole near those conditions is far from 22.4 L, recheck the units.
ווען װעט די װײַטער־געשיכטע װײַטער װײַזן?
It is very accurate at moderate pressures and temperatures well above the boiling point, but grows inaccurate at high pressure or near condensation, where molecular volume and attractions matter. Real-gas equations like van der Waals handle those.
ווי אַזוי האָט דער ענדערונג פֿון אַ װאַריאַבלע אַ השפּעה אויף די אַנדערע?
At fixed moles, pressure and volume are inversely related (Boyle’s law), while volume and absolute temperature are directly related (Charles’s law). Heat a sealed rigid container and the pressure rises in proportion to the kelvin temperature.
וואָס פֿאַרן באַטרעף פֿון R זאָל איך ניצן?
דאָס איז אַװעקגעקומען פֿון די יחידים. אין SI איז עס 8.314 J/(mol·K); אין ליטער־אַטמאָספערן איז עס 0.08206 L·atm/(mol·K). דאָס קאַלקולאַטאָר אַרבעט אין SI אינערלעכער מיט R = 8.314, אַזוי איר קענט אָנשרײַבן קיין יחידים און עס פֿאַרבינדט זיי
