Heat flows from a body of higher temperature to a body of lower temperature. Here the temperature of both the objects is the same. So, heat will not flow from one object to another or there will not be any change in the temperature of both the two objects.

Heat transfer between an iron ball and water
Introduction:
When two objects at different temperatures come into contact with each other, heat transfer occurs between them. The direction of heat transfer depends on the temperature difference between the objects. In this scenario, an iron ball at 40°C is dropped into a mug containing water also at 40°C. Let's analyze the possible heat transfer between the iron ball and water.
Explanation:
- When the iron ball is dropped into the water, the molecules of the iron ball and the water come into contact with each other.
- Heat transfer occurs due to the temperature difference between the iron ball and water.
- However, since both the iron ball and water are at the same temperature of 40°C, there is no temperature difference between them.
- According to the second law of thermodynamics, heat transfer occurs only when there is a temperature gradient (difference in temperature).
- In this case, as there is no temperature difference between the iron ball and water, heat will not flow from the iron ball to the water or from the water to the iron ball.
- Therefore, the correct answer is option 'B' - heat will not flow from the iron ball to the water or from the water to the iron ball.
Conclusion:
In the given scenario, since the iron ball and water are at the same temperature, there is no temperature difference between them. As a result, heat transfer does not occur between the iron ball and water.
