 What is heat? › Heat: Thermal energy moving from a warmer object to a cooler object. › When do you hear heat described? › Heat always travels from a __________ object to a ___________ object.

 3 ways… › Conduction › Convection › Radiation

 Heat transfers through a substance or from a substance to another by direct contact  Examples: › Raw egg fries as it hits a heated frying pan › Metal spoon in pot of hot water

 Heat transfer in liquids and gases as particles circulate in currents  Example: › When the water at the bottom of a pot is heated, it moves to the top. As the water rises, the surrounding cooler water flows into place.

 Transfer of heat through space in the form of waves.  Example: › Radiation of heat from a bonfire or lamp › The heat from the sun

 Conductor: material that transfers heat well. (pulls the heat to the outside) › Example: metals (stainless steel & silver)  Insulator: material that does not transfer heat well. (keeps the heat in) › Example: wood, wool, straw, paper, gases
