What is Thermal Energy?

o eat energy

oThe heat energy o! anobject determines howacti'e its atoms are.

* hot object is one whoseatoms and molecules aree#cited and show rapid

mo'ement.

* cooler object+s moleculesand atoms will show less

. Thermal energy

a. As temperature increases, so

does thermal energy (because thekinetic energy of the particlesincreased.

b. "en if the temperature doesn#tchange, the thermal energy in a moremassi"e substance is higher

(because it is a totalmeasure ofenergy.
