2. Explain Charles law in terms of the kinetic<br> molecular theory?
Alina [70]

Answer:

Explanation:

Charles law states that "the volume of a fixed mass of gas varies directly as its absolute temperature if the pressure is constant".

This law is a derivative of the kinetic molecular theory of gases.

  • The law explained shows that as the temperature of gases increases the volume of gases increases.
  • When gases are heated the average kinetic energy of the molecules increases.
  • The molecules are independent of one another and they begin to expand out as their velocity surges.
  • They take up more spaces in this way.
