Question

Statement 1: Heat capacity/Thermal capacity of a substance depends on mass of substance.
Statement 2: Specific heat capacity of a substance is independent of mass of substance.

• A. Statement 1 is correct, statement 2 is incorrect.
• B. Statement 1 is incorrect, statement 2 is correct.
• C. Both statements are correct.
• D. Both statements are incorrect.

Answer 1

The correct option is C Both statements are correct.

We know that,
Heat capacity is defined as amount of heat $\left(Q\right)$ required to raise the temperature of the whole body of mass $m$ through $1^{\circ }\text{C}$ or $1\text{K}$.
$\therefore$ It depends on mass of substance.
But,
Specific heat of substance is equal to heat gain or released by that substance to raise or fall its temperature by $1^{\circ }\text{C}$ for a unit mass of substance.
$\therefore$ It is independent of mass of substance.
