Chapter 3, Problem 3B.8P

(a)

Interpretation Introduction

Interpretation: The final temperature of the system has to be calculated.

Concept introduction: The physical quantity which is the ratio of the amount of heat transferred to a substance and the increase in temperature is called heat capacity.  If it is measured for one mole of substance, it is known as molar heat capacity.

(b)

Interpretation Introduction

Interpretation: The heat transferred to the copper block has to be calculated.

Concept introduction: The physical quantity which is the ratio of the amount of heat transferred to a substance and the increase in temperature is called heat capacity.  If it is measured for one mole of substance, it is known as molar heat capacity.

(c)

Interpretation Introduction

Interpretation: The entropy change of the copper block, water and total system has to be calculated.

Concept introduction: The randomness present in the system is called its entropy.  It is an extensive property.  At equilibrium, the entropy of the system is zero.  It is denoted by $S$.
