  • Thermal Physics
    • absolute temperature: the temperature at which the pressure of an ideal gas becomes 0
    • average kinetic energy of molecules increases? Temperature increases
      • absolute temperature: the temperature at which the pressure of an ideal gas becomes 0
    • effect transferred heat energy has on temperature depends on:
      • amount of heat energy transferred
        • E=MCAT in JKg-1K-1
      • mass of the object
        • E=MCAT in JKg-1K-1
      • specific heat capacity of material
      • internal energy: the total random distribution of kinetic and potential energy is a collection of particles
        • this internal energy is randomly distributed across all molecules according the the maxwell-boltzmann distribution
          • all have same mass, Ek dependent on speed [Ek=1/2mv2]
            • maxwell-boltzmann distribution shows that: * no molecules have 0 energy *only afew have high energies          * There is no maximum value for energy
              • two interesting speeds
                • most probable
                • root-mean-square speed
          • Each graph = one specific temperature
