  • Internal energy
    • thermal energy is transferred from higher temperatures to lower temperatures
    • energy change = mc*change in T
    • particles don't all travel at the same speed
      • As temperature increases, the average particle speed increases as well as the maximum speed, so the distribution curve becomes more spread out
    • Some collisions between particles are head-on, whereas others occur when particles move in the same direction but one is faster. So energy will be transferred between particles and between collisions, the particles will travel at a constant speed.
    • Internal energy is the sum of the kinetic and potential energy of the particles within a system
    • pV=nRT=Nm*mean square speed/3
      • m*mean square speed/2=3nRT/2N and so kinetic energy is proportional to temperature and internal energy
