Two objects A and B of different size are both at a temperature of 500 K and are connected by a rod (A looks four times larger than b). What will be the nature of transmission of heat?

A. Gradual transmission from B to A
B. No transmission of heat will occur
C. Rapid transmission from A to B
D. Rapid transmission from B to A

I'm leaning more on B, suggestions?

why would heat travel from one to the other if both are at the same temp?

I was right no heat is transferred

Yes.

To determine the nature of the transmission of heat between objects A and B, you can apply the basic principles of heat transfer. In this case, the nature of heat transfer can be determined by comparing the sizes, called thermal masses, of the two objects.

Given that object A is four times larger than object B, it has a higher thermal mass. The thermal mass of an object determines how much heat energy it can store. The larger the thermal mass, the more heat energy it can hold.

In this scenario, both objects are at the same temperature of 500 K. Heat energy naturally flows from a hotter object to a colder object until they reach thermal equilibrium. However, in this case, both objects are at the same initial temperature, so there is no temperature difference to drive the heat flow. Therefore, there will be no net transmission of heat between objects A and B.

Based on this analysis, your initial choice of option B, "No transmission of heat will occur," is correct.
