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 mintus error? mintu should have decreased the size of the metal iron. mintu should have decreased the time he touches the two metals. mintu should have chosen a material with a lower specific heat. mintu should have chosen a material the same temperature as the iron.

Answer

Explanation:

Step1: Recall heat - transfer principle

Heat transfer $Q = mc\Delta T$, where $m$ is mass, $c$ is specific heat, and $\Delta T$ is temperature difference. To increase heat transfer, we want a material that can absorb or release heat more easily. A material with a lower specific heat will change temperature more readily for a given amount of heat transfer.

Step2: Analyze Mintu's actions

Mintu wants to increase heat transfer. Increasing contact time and size of metal iron can help to some extent. But choosing a metal material with a higher specific heat is wrong. A material with a lower specific heat will allow for more heat transfer for a given temperature difference and mass.

Answer:

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