 Transfer of heat between objects in contact
with each other OR
 Between molecules that are within one object
 Vertical movement of fluids
 “Hot Air Rises” ………. And cools down
 Cold air sinks…. And heats up
 Horizontal movement of fluids
 The heating or cooling of a fluid (liquid or
gas)
 WITHOUT the addition or subtraction of heat
