How can I graph Charles' law?

Jul 2, 2014

Charles's 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's law is:

When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related.
this directly proportional relationship can be written as:

V $\alpha$ T or V/T = k
where:

$$V is the volume of the gas
T is the temperature of the gas (measured in Kelvin).
k is a constant.


This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can be written as:

${V}_{1}$ / ${T}_{1}$ = ${V}_{2}$ / ${T}_{2}$ or

${V}_{1}$ / ${V}_{2}$ = ${T}_{1}$ / ${T}_{2}$

Vary the temperature of the gas and records its new volume, at the new temperature. Get series of values of V and T. Plot V and T values to get Charles' law graph.
