⚗️Charles's Law Calculator (V₁/T₁=V₂/T₂)
Temperatures must be in Kelvin (K = °C + 273.15)
Charles's Law states that at constant pressure, the volume of an ideal gas is directly proportional to its absolute temperature (in Kelvin). V₁/T₁ = V₂/T₂. Heating a gas at constant pressure makes it expand.

Fun Fact
Jacques Charles discovered this law in 1787 while experimenting with hot-air balloons — a direct practical application. Hot air is less dense because it expands, generating lift.
