  1. 2. The random, erratic movement of microscopic particles in a fluid, providing evidence for the kinetic particle model of matter.
  2. 4. For a fixed mass of gas at constant volume, pressure is directly proportional to absolute temperature.
  3. 7. The energy required per unit mass to change the temperature of a substance by 1K or 1C.
  4. 8. A gas that obeys the equation pV=nRT or pV=NkT at all pressures, volumes, and temperatures.

  1. 1. The sum of the random distribution of kinetic and potential energies associated with the molecules of a system.
  2. 3. A state where two objects in contact have no net transfer of thermal energy between them, meaning they are at the same temperature.
  3. 5. For a fixed mass of gas at constant temperature, pressure is inversely proportional to volume.
  4. 6. The energy required per unit mass to change the state of a substance at a constant temperature.
