Atoms, Heat and Temperature SolidsLiquidsGases Atoms are perpetually in motion. Heat is the total kinetic energy of all the atoms in an object. Temperature is the average kinetic energy of the atoms.
Test Your Knowledge Which has more heat energy? The iceberg!!! Remember that heat is is the total kinetic energy of all the atoms in an object The iceberg is colder, but it has way more atoms!
Notes: Difference btwn Heat and Thermal Energy Heat: transfer of energy due to a temperature difference (conduction, convection, radiation) Thermal energy: total kinetic and potential energy of an object
Notes: Solids Particles are tightly packed, vibrating about a fixed position. Have a definite shape and a definite volume.
Notes: Liquids Particles are tightly packed, but are far enough apart to slide over one another. Have an indefinite shape and a definite volume.
Notes: Gases Particles are very far apart and move freely. Have an indefinite shape and an indefinite volume.
Notes: Plasma An ionized gas. A very good conductor of electricity and is affected by magnetic fields. Have an indefinite shape and an indefinite volume. The negatively charged electrons (yellow) are freely streaming through the positively charged ions (blue ).
