Question
A cold Object A is placed on top of a hot object B in a closed system. Identify which of the following is the best description of what occurs in the system?
I. Both A and B eventually reach the same temperature.
II. Gravity stops heat from moving up into A.
III. Heat flows from A to B

Solution
The correct option is A I only
When two bodies at different temperature are kept in contact with each other, then both the bodies finally acquire an equivalent temperature via heat flow.Also heat flows from hotter body to cooler body and gravity has no effect on the heat flow.Thus only statement I is true and hence option A is correct.
