A device that minimizes heat transfer is thermos. Technical name is vacuum flask.
<u>Explanation:</u>
Thermos is a bottle in which vacuum separates it from the surrounding. When the bottle is surrounded by the vacuum, there is a significant minimization in conduction.
The only part that having point of contact with the bottle inside is the thing which holds it in respective place. But there will be a small piece of contact, which will make the inner bottle to conduct heat to a small extent.
To find the unbalanced force you have to use the formula *net force=resultant force=unbalanced force =outside force).
