Question

heat always moves from a cooler object to a warmer one. objects create cold to balance out heat. heat always moves from a warmer object to a cooler one. heat and cold do not move between objects. what is the fundamental rule of how heat moves between objects?

Explanation:

Heat transfer occurs from a warmer object to a cooler one. This is a fundamental principle in thermodynamics. Heat always moves down the temperature gradient. For example, when you put a hot cup of coffee (warmer object) on a table (cooler object), heat from the coffee transfers to the table until thermal equilibrium is reached. The other options are incorrect. Heat does not move from cooler to warmer (unless work is done as in a refrigerator, but that's not the fundamental rule here). Objects don't "create cold" - cold is just the absence of heat relative to another object. And heat and cold do move (as heat transfer) between objects.

Answer:

Heat always moves from a warmer object to a cooler one.
