Radiation, Conduction, Convection Lyrics Chorus There are three ways that heat can travel But it can travel in any direction From the sun it moves to the earth, quick as a shadow And disperses in radiation, conduction, and convection Verse I First things first, let’s discuss heat What it is before you pay for it to warm your feet Heat is the energy that flows when atoms and molecules move It diffuses out toward coolness Temperature is the measurement of The average motion of these atoms And molecules in the atmosphere So there have it Now, the first way of transportation of heat energy is radiation Like sound waves from your radio stations Filling the empty space around you Your radiator warms you, but don’t start a fire now, I warned you Heat is going through radiation from the sun Before it burns you from 93 million miles away To re-radiate this heat is what the earth does for you This is survival what this heat is going through Before it rises to the sky and it’s gone so… Chorus Verse II Conduction is the second method on my list You can feel it like a hot pot on your fist With 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 heated Like a pan in the kitchen Transmit the heat energy to atoms next to them That are cooler than they are to cause equilibrium To even out the temperature the heat has to travel Up the spoon in your tea in the morning with your bagel It might burn your hand, but just learn the land of conduction heat energy until you understand The earth gains little from conduction It’s mostly radiation that helps us function and keeps us warm It’s just another way for heat to move But now let’s move on to method three to prove… Chorus Verse III Convection is the movement of heat in liquids and gasses To even out the temperature fastest This process is called diffusion It’s a flow of particles cold and hot in a fluid If you’re not listening, then stop what you’re doing ‘Cause this final mode that heat can move in And this affects you everyday It’s the breeze at your back and the wind at your face When heat reaches the earth it rises at a rate With the air in the place and it moves up till it cools Trillions of molecules together Make up the weather that we see on the news It’s how they measure the pressure of the air and the temperature But convection is how it got there in the atmosphere So don’t be scared. Heat moves in three ways So we made things clear, it’s like…
