From best to worst, rank these materials as heat conductors where 1 is the best and 3 is the worst: (a) copper wire, (b) snow, and a (c) glass rod.



Answer :

Answer:

The ranking is:

1. Copper wire

2. Glass rod

3. Snow

Or A→C→B

Explanation:

From best to worst, the ranking of these materials as heat conductors is as follows:

1. Copper wire: Copper is an excellent conductor of heat due to its high thermal conductivity. It is commonly used in electrical wiring and heat exchangers.

2. Glass rod: Glass is a poor conductor of heat compared to metals like copper, but it is still better than many non-metallic materials. Its thermal conductivity is much lower than that of copper.

3. Snow: Snow is an excellent insulator and a very poor conductor of heat. It traps air within its structure, which greatly reduces its thermal conductivity.
