Heat/Energy Review

QuestionAnswer
Fahrenheit The measurement unit for temp. used in the US
Conduction Heat transfer through solids-by colliding(direct contact, touch
Radiation Heat transfer through space
Heat Mover Moves thermal energy from one place to another
Heat Engine Device that converts thermal energy to mechanical energy
Insulator Material that heat does not flow easily through
Potential Energy Energy that is stored due to position
Kelvin Unit used to measure very cold temperature
Joule Unit used to measure energy
kinetic energy Energy of motion
Conductor Material that allows heat to flow easily
gravitational Potential Energy stored in object above the Earth's surface(rock on mountain) Ex: Apple falls out of a tree
Law of Conservation of Energy Energy changes form but none is lost-energy remains constant
Absolute Zero Temp where molecules slow to almost stop
Sun bather Radiation
iron on clothes Conduction
