Charles's Law
Charles' law (also known as the law of volumes) is an experimental gas law which describes how gases tend to expand when heated.
A modern statement of Charles' law is:
At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale (i.e. the gas expands as the temperature increases).
which can be written as:
where V is the volume of the gas; and T is the absolute temperature. The law can also be usefully expressed as follows:
The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

“I have seen in this revolution a circular motion of the sovereign power through two usurpers, father and son, to the late King to this his son. For ... it moved from King Charles I to the Long Parliament; from thence to the Rump; from the Rump to Oliver Cromwell; and then back again from Richard Cromwell to the Rump; then to the Long Parliament; and thence to King Charles, where long may it remain.”
—Thomas Hobbes (1579–1688)
“There is a law in each well-ordered nation
To curb those raging appetites that are
Most disobedient and refractory.”
—William Shakespeare (1564–1616)
