Chapter 10, Problem 27A

Interpretation Introduction

Interpretation: Among copper, silver and gold after applying 2.0kJ of heat the metal that achieve highest temperature needs to be determined.

Concept Introduction:Different materials have different heat capacities, so to adjust their temperature they require different amounts of energy.Specific heat capacity is the required energy to increase $1\text{g}$ of substances' temperature by $1°\text{C}$ .

Answer to Problem 27A

Specific heat capacity of gold is lower. So, it has highest temperature.

Explanation of Solution

Specific heat of copper, silver and gold is 0.385, 0.24 and 0.13 J respectively. For each metal, after applying 2.0kJ heat then observe the increase in temperature. Temperature increase depends on specific heat capacity. If the specific heat capacity is lower,then the temperature increase is higher, as specific heat capacity of gold is lower. So, its temperature is greater than other two.
