Question

Quizplus · Accepted Answer

Air is the poorest thermal conductor among the options listed. This is because air is a gas, and gases have molecules that are far apart, which makes it difficult for them to transfer heat through conduction. Solid materials like gold, copper, wood, and even ice have molecules that are much closer together, allowing them to conduct heat more effectively than air.
