Boltzmann Equation

Key points

  • Calculate the Kinetic Energy of a gas
  • The Internal Energy of an ideal gas consists only of its kinetic energy

The molecules of a gas move randomly with a range of speeds.

  • kb = Boltzmann constant
  • T = Temperature
  • EK = Kinetic Energy

Internal Energy of an ideal gas Equation/Formula IB

The Internal Energy of an ideal gas consists only of the random kinetic energy of its molecules

  • N = Number of Molecules
  • kB = Boltzmann constant
  • T = Temperature
  • Remember the basic rules that characterize an ideal gas
