Question

If you hold a piece of copper wire over the flame of a wooden match, heat will be conducted by the copper wire to your fingers, and you will be forced to drop the wire. You will, however, still be able to hold the match because wood is a poor conductor of heat.Which of the following is implied in the passage above?A. Copper is a good conductor of heat.B. Wood and copper conduct heat equaly.C. Wood is an excellent conductor of heat.D. Matches should be made of copper.

Answer 1

As the passage states, wood is a poor conductor of heat. Therefore, C is incorrect.

If it was true that wood and copper conduct heat equaly, both of them would be equaly hot too at the same time, but that doesn't happen. Therefore, B is incorrect too.

As the passage states, copper gets too hot too fast, so it wouldn't be a good material for matches as they would burn too fast and burn our fingers too. Therefore, D is wrong as well.

Because copper conducts the heat so fast until it gets to our fingers, we can say that it is a good conductor of heat. Therefore, the correct answer is A. Copper is a good conductor of heat.
