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
Answer
Brief Explanations:
Heat transfer is proportional to the contact - area between two objects. Thermal equilibrium stops heat transfer. Similar specific heats don't directly increase heat transfer. Reducing contact time decreases heat transfer.
Answer:
increasing the area of their contact
