Question

Mintu wants to increase the heat transfer between a metal iron and another piece of metal he wants to shape. He decides to increase the time the two metals are in contact, use a larger metal iron, and use a new metal material with a higher specific heat. Where is Mintu's error?
A) Mintu should have decreased the size of the metal iron.
B) Mintu should have decreased the time he touches the two metals.
C) Mintu should have chosen a material with a lower specific heat.
D) Mintu should have chosen a material the same temperature as the iron.

Answer 1

Answer:

Mintu should have chosen a material with a lower specific heat.

Explanation:

When we talk about specific heat, we refer to a specific quantity of heat that is needed for a substance or material to rise its temperature. In more concrete terms, is the amount of heat required for 1 gram of substance/material to elevate its temperature by 1 degree Celsius.

This would mean that a material with a high specific heat would require a higher quantity of heat to increase its temperature, so in this case, if Mintu wanted to make the heat transfer easier between the metal iron and the other piece of metal, he should have chosen a material that could elevate its temperature by receiving a lower quantity of heat, that is a material with a low specific heat. But instead he chose a metal with a higher specific heat, which will now make the heat transfer more difficult,and that was the error.
