Question

Two objects A and B of different size are both at a temperature of 500 K and are connected by a rod as in the image below. What will be the nature of transmission of heat?

A B
______
| | ---------
| | --------> | |
---------- ---------
500 K 500 K

Answer 1

Heat transfer occurs from a hotter object to a colder one, but since both objects A and B are at the same temperature of 500 K, there will be no net heat transfer between them.

Step-by-step explanation:

The question pertains to the heat transfer between two objects of different sizes but at the same temperature, specifically examining if there will be transmission of heat between them. According to the principles of thermodynamics, heat transfer occurs from an object at a higher temperature to an object at a lower temperature. In the scenario described, both objects A and B are at a temperature of 500 K. Since they are at the same temperature, there will be no net heat transfer between the two objects through the connecting rod; the system is in thermal equilibrium. If we assume no external temperature difference or heat source/sink, both objects will remain at 500 K, and no spontaneous heat flow will take place.
