Final answer:
A thermally thin object refers to an object that loses heat rapidly. In this case, the thin sheet of paper is considered to be thermally thin and has the highest heat loss capability.
Step-by-step explanation:
A thermally thin object refers to an object that loses heat rapidly. A thermally thin object refers to an object that loses heat rapidly. In this case, the thin sheet of paper is considered to be thermally thin and has the highest heat loss capability.
In this case, the object with the highest heat loss capability is the thin sheet of paper (option B). Thin materials have a smaller thermal conductivity, which means that they can transfer heat more easily. For example, if you hold a thin sheet of paper near a flame, it will quickly burn due to its ability to conduct heat.
