Question

How does heat transfer happen in conduction?

(A) A hotter object passes thermal energy to a colder object by touching it so their particles bump into each
other.
(B) A hotter object reaches thermal equilibrium and gives its extra heat particles away to nearby objects.
(C) A hotter object is placed on one side of an insulator and a colder object is placed on the other side of
the insulator.
(D) A hotter object has particles that spread through the air as gases and warm the air near the colder
object.

Answer 1

(A) conduction implies that the objects are in contact
