Thermal energy
The transfer of energy by direct contact.
conduction.
A material that allows heat to move through it.
Conductor
instrument used to measure temperature.
thermometer
Which has less kinetic energy in its particles? An object that is 0 degrees Celsius or one that is 15 degrees Fahrenheit.
