WhatisThermalEnergy?

Thermalenergyisaformofenergythatarisesfromthemotionofparticlesinmatter.Thismotioncaneitherbetranslational,rotational,vibrational,oracombinationofthese.Morespecifically,thermalenergyisaproductofthekineticenergyofatomsandmoleculesinasubstance.Thefastertheseparticlesmove,thehigherthethermalenergyofthesubstancebecomes.Allmatterhassomethermalenergy,whichmeansthatevenobjectsthatappearcoldorstationarycontainsomelevelofthermalenergy.

HowDoesThermalEnergyWork?

Thermalenergyoperatesthroughthetransferofheatbetweenobjects.Heatisaformofenergythatmovesfromareasofhightemperaturetolowtemperature.Whentwoobjectswithdifferenttemperaturescomeintocontact,heatenergyflowsfromthehotterobjecttothecooleroneuntiltheyreachastateofthermalequilibrium,whentheirtemperaturesbecomeequal.

Onecommonexampleofthermalenergyistheheatingofwater.Whenapotofwaterisplacedontoahotstove,heatenergyfromthestovetransferstothewatermolecules,increasingtheirkineticenergy.Asthemoleculesmovefaster,theycollidewitheachothermorefrequently,whichincreasesthetemperatureofthewater.Eventually,thewaterbecomeshotenoughtoboil,andthewatermoleculesbegintochangestatefromliquidtogasduetotheincreasedthermalenergy.
