• Bell ringer (written): Give examples of conduction, convection, and radiation.

  • Review conduction, convection, and radiation

  • Thermodynamics - the study of heat and heat transfers

    • 1st law of thermodynamics: Conservation of energy - the total amount of energy in a system does not change. The energy can change types or change locations, but the amount of energy remains constant.

    • 2nd law of thermodynamics: entropy - energy tends to spread out over time. This means that heat will not flow from something cold to something warm unless we do work to make this happen.

    • 3rd law: It is impossible to reach a temperature of absolute zero.
