Problem
A student claims, "When a hot iron rod is placed in cooler air, the air particles speed up because heat flows from the rod into the air, and this continues until the air transfers heat back to the rod so both reach the same temperature." Identify the misconception in the student's statement and correct it with a concise molecular-level explanation of how energy actually flows in this situation.
