Question

which of these actions would increase heat transfer between two objects? establishing their thermal equilibrium increasing the area of their contact using objects with similar specific heats reducing the time of their contact

Explanation:

• Thermal equilibrium means no net heat transfer, so establishing it won't increase heat transfer.
• Using objects with similar specific heats doesn't directly increase heat transfer.
• Reducing contact time reduces heat transfer.
• According to the formula for heat transfer (e.g., in conduction \(Q=\frac{kA\Delta T d t}{L}\), where \(A\) is the area of contact), increasing the area of contact (\(A\)) increases the heat transfer (\(Q\)).

Answer:

increasing the area of their contact
