Charles's law

An animation demonstratin the relationship atween volume an temperatur.

Charles' law (an aa kent as the law o volumes) is an experimental gas law that describes hou gases tend tae expand when heatit. A modren statement o Charles' law is:

When the pressur on a sample o a dry gas is held constant, the Kelvin temperatur an the volume will be directly relatit.

this directly proportional relationship can be written as:

$V\propto T\,$

or

${\frac {V}{T}}=k$

whaur:

V is the volume o the gas

T is the temperatur o the gas (meisurt in Kelvin).

k is a constant.
