Question

If the average kinetic energy of substance A's molecules is higher than the average kinetic energy of substance B's molecules:

Thermal energy will be transferred from substance B to substance A.

The temperature of substance B will be higher than substance A.

Heat will transfer from substance A to substance B.

The temperature of substance A is lower than that of substance B.

Answer 1

Answer:

Heat will transfer from substance A to substance B.

Explanation:

Since the average kinetic energy of substance A's molecules is higher than the average kinetic energy of substance B's molecules, it means substance A has a higher temperature than substance B because an increase in temperature will increase the average kinetic energy of molecules.

Since substance A has higher temperature than substance B, therefore, heat will be easily transferred from substance A to substance B
