Question

question 8 of 28 how does conduction transport heat through a steel rod that is placed in a fire? a hot steel molecules move down the molecular matrix toward the cool end of the rod. b waves of electromagnetic energy travel down the steel rod from one end to the other. c higher velocities of warmer steel molecules cause them to travel from one end to the other. d energy spreads from one end of the rod to the other through molecular collisions.

Explanation:

Conduction in a steel rod transfers heat via molecular collisions, where energy spreads from the hot end to the cool end through interactions between adjacent molecules.

Answer:

D. Energy spreads from one end of the rod to the other through molecular collisions.
