## Ideal Gas Law The ideal gas law relates the pressure, volume, temperature, and amount of a gas. ### Formula **PV = nRT** where R = 0.082057 L·atm/(mol·K) or 8.314 J/(mol·K). This law is accurate for gases at moderate pressures and temperatures.
हल किया गया उदाहरण
1 mole of gas at 273.15 K (0°C) in 22.414 L (STP conditions).
- 01P = nRT / V
- 02P = 1 * 0.082057 * 273.15 / 22.414
- 03P = 22.414 / 22.414
- 04P = 1.000 atm (as expected at STP)
अक्सर पूछे जाने वाले प्रश्न
What is an ideal gas?
A theoretical gas with perfectly elastic collisions and no intermolecular forces. Real gases approximate ideal behavior at low pressures and high temperatures.
What is STP?
Standard Temperature and Pressure: 273.15 K (0°C) and 1 atm. At STP, one mole of ideal gas occupies 22.414 liters.
When does the ideal gas law fail?
At very high pressures or low temperatures, where intermolecular forces and molecular volumes become significant. The van der Waals equation corrects for this.
