Question

Specific heat capacity is ______ for conductors of heat and _______ for insulators of heat.

• A. low, low
• B. low, high
• C. high, high
• D. high, low

Answer 1

The correct option is B low, high

$Q=ms\Delta T$,

where

$Q:\text{the amount of heat delivered to a body}$

$m:\text{mass of the body}$

$s:\text{specific heat capacity of the body}$

$\Delta T:\text{Change in temperature of the body}$

If $Q\text{and}m$ are constant,

$\Delta T\propto \frac{1}{s}$

So for small $s,\Delta T$ is more and hence it is better conductor of heat.
