Science
Ideal gas law.
Definition
An equation of state that relates the pressure, volume, temperature, and number of moles of an ideal gas. It combines Boyle's law, Charles's law, and Avogadro's law into a single equation. Real gases behave most like ideal gases at high temperatures and low pressures.
Examples
Real-world.
- 1 Calculating the volume of a balloon at different altitudes
- 2 Determining the pressure inside a scuba tank
- 3 Predicting how a gas sample responds to temperature changes
Key Fact
PV = nRT, where R = 0.0821 L·atm/(mol·K) or 8.314 J/(mol·K)
