The Ideal Gas Equation
The Ideal Gas Law relates the macroscopic properties of ideal gases. An ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
PV = nRT
- P: Pressure
- V: Volume
- n: Amount of substance (moles)
- R: Ideal Gas Constant (0.0821 L·atm·K⁻¹·mol⁻¹)
- T: Absolute Temperature (Kelvin)
