Temperature
Average Kinetic energy of the particles in a substance
Thermal energy
Sum of kinetic and potential energy
Heat
A transfer of thermal energy
Moves from high to low thermal energy
Conduction
Energetic particles colide with slower particles, giving them kinetic energy.
Dominant method of heat transfer in solids
Convection
A local region at higher temp has less density than a colder region. Lower density = Lower mass. Heavy sinks, than heats to the top and cools e.t.c.
Dominates fluids (S&G)
Radiation
Heat transfer through electromagnertic waves. Requires no medium.
Dominant form in space.
Temperature scale units:
C Celcius, K Kelvin (No degree symbol). Constructed around absoloute zero.
Absolute zero
No particle movement. -213.15 * C or 0K
What is Q and what unit
Thermal energy Joules
Power
Work over time
Wattage
W
