Two samples of carbon come into contact. A heat transfer will occur between sample A and sample B. What must be true for heat to transfer from sample A to sample B?
Answer
A
The average kinetic energy of A is greater than that of B.
B
The average kinetic energy of B is greater than that of A.
C
The average kinetic energy of both samples is equal.
D
The average kinetic energy does not determine the direction of heat transfer.
