Ideal Gas Law (PV = nRT)
P·V = n·R·T
What it means
The ideal gas law connects the pressure, volume, amount, and temperature of a gas — essential in thermodynamics and chemistry.
Variables
| Symbol | Quantity | SI unit |
|---|---|---|
P | pressure | Pa |
V | volume | m³ |
n | moles | mol |
R | gas constant | J/(mol·K) |
T | temperature | K |
Worked example
Given n = 1 mol, R = 8.314 J/(mol·K), T = 300 K, V = 0.025 m³, solve for P:
P = 99768 Pa
