Jacques charles law biography definition

Charles’s law or the law of volumes is an ideal gas law that states that the volume and temperature of a fixed amount of gas are proportional at constant pressure.

Jacques charles law biography definition

Doubling the temperature of a gas doubles its volume. Halving the temperature of a gas halves its volume. The law takes its name from French scientist Jacques Charles, who formulated the law in the 1780s.

Charles’s law states that increasing the temperature of a gas at constant pressure increases its volume.

Charles’s Law Formula

There are a few ways to state Charles law as a formula:

V ∝ T
V/T = k
V = kT
V₁/T₁ = V₂/T₂
V₂/V₁ = T₂/T₁
V₁T₂ = V₂T₁

Here, T is absolute temperature, V is volume, and k is a non-zero constant.

Note that absolute temperature means Celsius and Fahrenheit temperature must be converted to Kelvin. The graph of volume versus pressure shows the linear relationship. Also, the line points toward the origin, although a gas could never reach it because it
