Grade 8 PS Physics: Thermal Energy

Flashcards for Mr. Barkouras's Thermal Energy Test

thermal energy

the total kinetic and potential energy of all the particles in an object

particles

atoms, molecules, or compounds in an object

heat

the transfer of thermal energy from a warmer object to a cooler object

heat always flows from…

a high temperature object to a low temperature object

when an object loses heat, it…

decreases in temperature

when an object gains heat, it…

increases in temperature

temperature

the measure of the average kinetic thermal energy (speed) of the particles of a substance.

faster particles —> greater energy —>

greater temperature

absolute zero

the lowest possible temperature, where temperature atoms are motionless

absolute zero in kelvin

0K

absolute zero in celsius

-273C

absolute zero in fahrenheit

-460C
