Below are the answers to 2016-2017 CP Review HW for Energy and Dimensional Analysis Test. The questions were answered in a clear and concise manner, in complete sentences when appropriate.
1. Thermodynamics is the study of movement of energy.
2. Movement of energy
3. Ok and a perfect crystal (substance with only one type of atom)
4. Energy is never "lost" (per the 1st Law of Thermodynamics), in this case "lost" means the system is releasing energy to the surroundings (ever place else in the Universe ecept the system).
5. Calories (cal) and Joules (J). K = °C + 273 or K is always larger than °C by 273
6. KE is the energy of movement. Sound energy and wave energy.
7. (Verbatim) Temperature is the average KE of all the particles in the substance.
8. The basis of the Absolute temp scale is Absolute zero.
9. the ° sign
10. Freezing point (FB) and boiling point (BP) of water.
11. No, temperature and heat are not same thing. Heat is a form of total energy whereas Temp is the average KE of all the particles in a substance.
12. Activation Energy is the minimum amount of energy needed for a set of reactants to form a set of products.
13. Positive ("+") sign
14. Less than
15. Discuss in class
16. Calorimetry is the theory that you can use a single phase substance to measure how much energy is flowing. The calorimeter is the device to do this function. Specific heat capacity is how much energy it takes to raise the temp of substance (specifically 1g) by 1 °C. It explain how quickly or slow energy is absorbed/released by a substance.
