Went over SHM test.

Went over RA 14.1.
Temperature scales: Fahrenheit, Celsius, Kelvin
Kelvin: don't say "degrees" Kelvin. Kelvin scale MUST be used if the temperature is and absolute temperature and not a temperature difference, as in the ideal gas law, PV = nRT
Internal Energy: Total energy of all the particles
Heat: Energy that flows from one object to another based on temperature difference
Temperature: Measure of how "hot" or "cold". Measure of the average random kinetic energy.
Difference between internal energy and temperature

Degrees of freedom: monoatomic, diatomic with rotational modes, metallic crystal with KE and PE
Heat Capacity: On average, energy is shared equally between all degrees of freedom and between all particles.

Collected RA 14.2
Handed out RA 14.3 - due Wednesday
Assigned WebAssign Chapter 14 due Fri
Oleic Acid due Wednesday
