Question 8 • VJSHS - Chemistry (Full Year)

Which statement best describes the direction of heat flow by conduction between two samples of the same material?

Answer

A

Heat flows from faster molecules to slower molecules when they are near.

B

Heat flows from faster molecules to slower molecules when they collide.

C

Heat flows from slower molecules to faster molecules when they are near.

D

Heat flows from slower molecules to faster molecules when they collide.

Explanation

Conduction transfers thermal energy through collisions between nearby particles. Faster-moving molecules have more kinetic energy, so during collisions they transfer energy to slower-moving molecules. Thus, heat flows from faster molecules to slower molecules when they collide.
