Conduction
Term | Definition |
---|---|
Conduction | The process of heat transfer MOSTLY in a solid (but can happen in liquid) through direct contact. |
How does heat flow between objects that are in direct contact? Does it flow from hot to cold or cold to hot? | hot to cold |
Which way does heat flow? A spoon with fast moving molecules holding a scoop of ice cream with slow moving molecules. (spoon to ice cream OR ice cream to spoon) | spoon to ice cream |
Heat flow from hot to cold until it is the ________(same or different) temperature in both objects that are in direct contact. | same |
Heat energy flows from ________________________ materials | warmer to cooler |
Temperature must be _____________(different or same) in order for heat to flow in the objects that are in direct contact. | different |
Which way does heat flow? A spoon with slow moving molecules inside of a cup of soup with fast moving molecules. (soup to spoon OR spoon or soup) | soup to spoon |
Which way does heat flow? A hand with fast moving molecules holding and a metal fork with slow moving molecules. (hand to fork OR fork to hand) | hand to fork |
Heat will NOT flow if the objects were of the _____________(same or different) temperature. | same |
Heat will ONLY flow if the objects were of the __________(same or different) temperature. | different |
Which way does heat flow? A hand with fast moving molecules holding and a phone with slow moving molecules. (hand to phone OR phone to hand) | hand to phone |
Why does conduction not work at all in gas? | The molecules are NOT compacted together enough to transfer the energy to another object. |
Why does conduction work very well in solid? | The molecules are compacted together enough to transfer the energy to another object. |
Which way does heat flow? A sock with FAST moving molecules covering a foot with FASTER moving molecules.( sock to foot OR foot to sock) | foot to sock |
Heat flows FASTER when the objects in direct contact are of ____________(same or different) temperatures. | different |
