Which property makes a substance a good conductor of heat?

Question

a. if heat is unlikely to escape to its surroundings
b. if heat moves through it quickly
c. if its particles are farther apart
d. if its particles are unlikely to bump together

Answer 1

The correct answer is b. if heat moves through it quickly.

A good conductor of heat allows thermal energy to transfer rapidly from one part of the material to another, which is characterized by the ability of its particles to efficiently transfer kinetic energy through collisions.
