Heat Transfer. It’s Hot!!! Heat “flows” from Hot to Cold! Which is the same as saying energy goes from areas of high energy density to areas of low energy density… it spreads out!. Temperature. The average Kinetic Energy of a substance Everything is wiggling!!!!!. Entropy.

**Heat Transfer**• It’s Hot!!! • Heat “flows” from Hot to Cold! • Which is the same as saying energy goes from areas of high energy density to areas of low energy density… it spreads out!**Temperature**• The average Kinetic Energy of a substance • Everything is wiggling!!!!!**There are 3 kinds of Heat Transfer**• Conduction • Convection • Radiation**Convection at work**• Heating up a fluid causes its density to decrease – it is more bouyant, so it moves up. Cooler material is denser and moves down.**Just like in Kona! The sun heats up the mountain, the air**moves upslope – and condenses to form clouds – keeping the coffee plants shaded!**Conduction**• Atom to Atom energy transfer – some are better than others at moving energy • Bi-Metallic strip demo**Radiation**• Electromagnetic Radiation • Infrared**Boiling Melting**• Condensation Radiation • Conduction Sublimation • Convection Phase • Evaporation Phase change • Freezing Absorption • Heat of fusion Entropy • Heat of vaporization
