Question

Equal amounts of heat is supplied to two bodies A and B of same mass made of different materials. Body A shows more temperature rise as compared to body B. Which of the following statements is true?

• A. Body A has higher specific heat than body A.
• B. Body B has higher specific heat than body A.
• C. Body A has same heat capacity as body B.
• D. Body B has half the heat capacity as body A.

Answer 1

The correct option is B Body B has higher specific heat than body A.

From defintion of specific heat,
$C=\frac{Q}{\Delta Tm}$
where
$C:\text{Specific heat}$
$\Delta T:\text{Temperature rise}$
$m:\text{Mass}$

Body B shows more reluctance to temperature change, i.e, for the same heat supplied and for the same masses of the bodies A and B, temperature rise is less significant in B. Hence, specific heat of body B is more than A.
