Which of the following describes conduction?

Question

Group of answer choices

the sum of all the kinetic energies of all the molecules of an object

the amount of heat necessary to raise one mass unit of that substance by one temperature unit

the average kinetic energy of the molecules of an object

the movement of heat from one object to another by molecular collision

Answer 1

The option that describes conduction is:

the movement of heat from one object to another by molecular collision.

Conduction is the process of heat transfer through direct contact between molecules, where heat moves from the hotter region to the cooler region as molecules collide and transfer energy.
