Chapter 3, Problem 91CP

Interpretation Introduction

Interpretation: The following problem can be comprehended by the concept of heat.

Concept introduction: Heat capacity is a physical quantity which is equal to the ratio of heat given to (or taken from) the object to the resultant change in temperature. Its SI unit is Joule/ Kelvin. It is an extensive attribute of matter. When the heat capacity is calculated per unit mole for a substance, it is called molar heat capacity while it is called specific heat capacity or specific heat, when it is measured per unit mass for a substance. For a particular substance, heat capacity is directly proportional to the quantity of the substance present. Yet the specific heat is an attribute of the structure of a substance. It depends on the number of available degrees of freedom in the particular substance, which permits the particles of the substance to accumulate thermal energy.
