which of these actions would increase heat transfer between two objects?\nestablishing their thermal equilibrium\nincreasing the area of their contact\nusing objects with similar specific heats\nreducing the time of their contact
Answer
Brief Explanations:
Heat transfer is proportional to the contact - area between two objects. Establishing 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
