Chapter 12, Problem 72A

a.

To determine

To Complete: The problem using the concept of specific heat.

Explanation of Solution

Introduction:

Specific heat of a material is the amount of heat required to raise the temperature of a gram of the substance by a degree Celsius.

A question to be solved using the concept of specific heat is as follows:

A beaker of water has a temperature of $35°\text{}\text{C}$ containing $\text{50 g}$ of water. Calculate the amount of heat required to raise the temperature of water to $\text{50}°\text{ C}$ ?

b.

To determine

To Complete: The problem using the concept of entropy.

Explanation of Solution

Introduction:

Entropy of a system is the measure of disorder in the system. Entropy of a system never decreases, it either increases or remains constant.

A question to be solved using the concept of entropy is as follows:

A beaker of water has a temperature of $35°\text{}\text{C}$ containing $\text{50 g}$ of water. Calculate the change in entropy when the water is heated to $\text{50}°\text{ C}$ ?
