Question
Body A and body B are in thermal contact and are in thermal equilibrium. Which of the following is true? In thermal equilibrium
(a) the total amount of energy
due to atomic motion is the same in A as it is in B
(b) each of the atoms in A and in B have exactly the
same amount of energy, at any instant
(c) the atoms
in both A and B stop moving
(d) the average amount of energy transferred by atomic collisions from A to B is the same as the average amount transferred from B to A from instant to instant
please explain the answer
Explanation / Answer
(d) the average amount of energy transferred by atomic collisions from A to B is the same as the average amount transferred from B to A from instant to instant
As the question itself states that A and B are in thermal equlibrium
