Ch. Heat Flashcards
Solids -
Forces can be though of as springs that connect neighboring atoms
Liquids -
Forces are weaker
Gases -
Forces are very weak, Almost negligible
No matter what the phase…..
Aromas are always in motion
Tells how hot or cold something is compared to a standard
Temperature
How to get to kelvin -
C + 273
Not all particles in an object have …..
Same energy
The energy that is transferred from one object to another because of temp difference between the two
Heat
Matter contains energy, NOT …
Heat
Heat flows from …..
High to low
Energy resulting from heat flow -
Thermal energy
Grand total of all the energies inside a substance
Internal energy
Heat flow from one object to another when in contact
Thermal contact
When objects in thermal contact reach the same temp
Thermal quilibrium
Energy transferred from particle to particle within certain materials or from one material to another when the two are in direct contact
Conduction
Conductor -
Material that conducts heat well
Insulator
Poor conductor of heat & delays transfer of heat
Heating occurring by currents in a fluid -
Convection
How is wind caused?
By convection currents due to uneven absorption of heat by land/water
Energy transmitted by electromagnetic radiation -
Radiation
Any energy that is transmitted by radiation
Ex. Cell phone towers, fire place
Radiant energy
