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.
