Charles's Law !
- The French physicist Jacques Charles studies the relationship between volume and temperature. He observed that as temperature increases, so does the volume of a gas sample when the pressure is held constant.
- This process can also be related to the Kinetic-Molecular Theory, mainly because at higher temperatures gas particles move faster and they strike each other and the walls of their container more frequently with greater force.
- For the pressure to stay constant the volume must increase so that these particles have farther to ravel before striking any walls.
- Charles's Law states that the volume of a given mass of gas is directly proportional to its kelvin temperature at constant pressure. This can be expressed with the following formula.
__V1__ = _V2__
T1 T 2
