FLASHCARD QUESTION
Front
Thermal Energy Noun
[thur-muhl en-er-jee]
Back
Thermal Energy
The total internal energy of a substance, resulting from the random motion of its atoms and molecules.
Example: Molecules in a hot area move faster, transferring thermal energy to a cooler area.

FLASHCARD QUESTION
Front
Kinetic Energy Noun
[ki-net-ik en-er-jee]
Back
Kinetic Energy
The energy an object or particle possesses because of its motion; faster movement means more kinetic energy.
Example: A roller coaster moving down a track shows kinetic energy as it speeds up.

Temperature Noun
[tem-per-uh-cher]
Back
Temperature
A measure of the average kinetic energy of the individual atoms or molecules within a particular substance.
Example: Particles in warmer areas move faster, showing higher temperature and energy.

FLASHCARD QUESTION
Front
Molecule Noun
[mol-i-kyool]
Back
Molecule
The smallest particle of a substance, made of two or more atoms chemically bonded together, that retains its properties.
Example: The image shows a water molecule, with two hydrogen atoms bonded to one oxygen atom, illustrating how molecules are made of atoms bonded together.
