Expansion
An increase in volume due to a pull force or heating
Kinetic energy
Energy of motion
Thermometer
Tool used to measure the average kinetic energy of matter
Energy Transfer
Movement of energy from one place to another
Conduction
The transfer of heat NRG from one particle to another as result of contact/collisions
Temperature
The average kinetic energy of a substance
Formula for Temperature Final
(T hot + T cold) divided by 2
