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.

Option (C) is the correct answer.

Explanation:

The amount of heat necessary to raise the temperature of 1 gram of a substance by is known as specific heat of a substance.

Mathematically,     q =

where,    q = Heat energy

               C = specific heat

          = change in temperature

Hence, smaller is the amount of heat required by a substance to raise the temperature of its 1 g by more readily it will get hot.

Therefore, out of the given options specific heat of copper is small. So, copper will heat up quickly.

Thus, we can conclude that Mintu's error is that Mintu should have chosen a material with a lower specific heat.

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