Today in class, besides Mr.Tucker's cheesy jokes that he thinks are great, We took notes on Thermochemistry/Energy.
Here are the notes:
1. Temperature-
Average kinetic energy of the particles in a substance.
Units Used: Fahrenheit( we don't use this in class), Celsius and Kalvin.
2. Heat-
Transfer of Energy (joules).........Can be gained or lost.
Tuckers Joke: " There's also dominicks and walgreens".....yaaaa? no comment
3. Heat loss and Gain
Endothermic- Gaining heat
Exothermic- Loosing Heat.
In between notes we did a quick observation of Mr Tuckers " Magic Blocks." One block was wood and one was metal. The wood block was warm, compared to the metal block. After putting a piece of ice on both blocks, the ice melted faster on the metal block!! This was all due to the energy transfer.

Part1.A Heating and Cooling of a solid
Heat (q)= M * Cp ΔT (Tf-Ti)
Part2B Melting solid <-> Liquid freezing
Heat= M * HF
Part3C Heating/Cooling a Solid
Heat (q)= M * Cp ΔT (Tf-Ti)
Part 4D Boil a liquid <-> Gas condenses
Heat= M * HV ( Heat Vaporization )
Part5E Heating/Cooling a Gas
Heat (q)= M * Cp ΔT (Tf-Ti)
