Relate gas volume and absolute temperature at constant pressure.
V₁/T₁ = V₂/T₂
Formula Explanation
For a fixed amount of ideal gas at constant pressure, volume is proportional to kelvin temperature.
Variables Explained
V₁, V₂ = Volumes; T₁, T₂ = Absolute temperatures in kelvin.
Solved Example
A gas occupies 2 L at 300 K. Find its volume at 450 K at constant pressure.
V₂ = 2 × 450 / 300 = 3 L.
