Question

Conductors become hot easily because they have:

• A. high specific capacity
• B. low specific heat capacity
• C. high freezing point
• D. low freezing point

Answer 1

Answer: (B)

low specific heat capacity

In conduction, heat is transferred by the vibrations of molecules. The density of conductors is large, it means molecules are close to each other. Because of that they can easily transfer the heat quickly throughout the whole volume of the conductor. Thus, less heat is needed to raise the temperature of unit mass of the conductors by $1^{o}C$. This heat is called specific heat capacity. Therefore conductors become hot easily on account of low specific heat capacity.
