Radiation, Conduction, Convection• Lyrics• Chorus
There are three ways that heat can travelBut it can travel in any directionFrom the sun it moves to the earth, quick as a shadowAnd disperses in radiation, conduction, and convection
Verse IFirst things first, let’s discuss heatWhat it is before you pay for it to warm your feetHeat is the energy that flows when atoms and molecules moveIt diffuses out toward coolness
Temperature is the measurement ofThe average motion of these atomsAnd molecules in the atmosphereSo there have it
Now, the first way of transportation of heat energy is radiationLike sound waves from your radio stationsFilling the empty space around youYour radiator warms you, but don’t start a fire now, I warned youHeat is going through radiation from the sunBefore it burns you from 93 million miles awayTo re-radiate this heat is what the earth does for youThis is survival what this heat is going throughBefore it rises to the sky and it’s gone so…
Chorus
Verse IIConduction is the second method on my listYou can feel it like a hot pot on your fistWith the handle gripped I bet you’d rather grab a candle lit‘Cause it’s heat through conduction that causes this
•
Atoms in matter in a fixed position vibrate when heatedLike a pan in the kitchenTransmit the heat energy to atoms next to themThat are cooler than they are to cause equilibriumTo even out the temperature the heat has to travelUp the spoon in your tea in the morning with your bagelIt might burn your hand, but just learn the land ofconduction heat energy until you understandThe earth gains little from conductionIt’s mostly radiation that helps us function and keeps us warmIt’s just another way for heat to moveBut now let’s move on to method three to prove…
Chorus
Verse IIIConvection is the movement of heat in liquids and gassesTo even out the temperature fastestThis process is called diffusionIt’s a flow of particles cold and hot in a fluidIf you’re not listening, then stop what you’re doing‘Cause this final mode that heat can move inAnd this affects you everydayIt’s the breeze at your back and the wind at your face
When heat reaches the earth it rises at a rateWith the air in the place and it moves up till it coolsTrillions of molecules togetherMake up the weather that we see on the newsIt’s how they measure the pressure of the air and the temperatureBut convection is how it got there in the atmosphereSo don’t be scared. Heat moves in three waysSo we made things clear, it’s like…
