Sagot :
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.
