Why does temperature change always move from regions of hot to regions of cold?

Question

Responses

A because hotter particles can not slow downbecause hotter particles can not slow down

B because colder particles have more potential energybecause colder particles have more potential energy

C because kinetic energy is transferred in the collisions of particlesbecause kinetic energy is transferred in the collisions of particles

D because this is the fastest, most efficient means of conducting thermal energy

Answer 1

The correct response is:

C. because kinetic energy is transferred in the collisions of particles.

Temperature changes occur as thermal energy (or heat) is transferred from regions of higher temperature (where particles have higher kinetic energy) to regions of lower temperature (where particles have lower kinetic energy) through collisions between particles. This process continues until thermal equilibrium is reached.
