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

   The correct answer is :  increasing the area of their contact

Explanation:  Heat transfer between two substances is affected by specific heat and the  amount of time and area of physical contact between the substances. The transmission or transfer of heat that is based on the direct contact of bodies or objects, is called driving and there is only energy transfer. There are materials that conduct heat very well like gold, silver and copper.
