Question

Specific heat capacity of a substance is independent of __________.

• A. mass
• B. temperature
• C. volume
• D. all of these

Answer 1

The correct option is D

all of these

The explanation for Correct Options:

Option A

1. The specific heat capacity is defined as the quantity of heat absorbed per unit mass of the material when its temperature increases by $1K$
2. The formula for Specific Heat is $c=\frac{Q}{m∆T}$
3. As it is the heat absorbed by the unit mass of the substance it is independent of mass.

Option B

1. Specific heat capacity is the heat absorbed in the unit increase in temperature.
2. Thus it does not depend on temperature as well.

Option C

1. Volume is defined as $volume=\frac{mass}{density}$
2. Since specific heat capacity does not depend on mass and density of any material is an intrinsic property.
3. Therefore specific heat capacity is independent of volume as well

Option D

Hence all the above options are correct.
