प्रश्न
Does the specific heat capacity of a substance depend upon its mass and rise in temperature only?
उत्तर
No, for the same mass and for the same rise in temperature for different substance, the specific heat capacity is found to be different. Thus, specific heat capacity depends upon the nature of the substance also and so its is different for different substances.
