Observe the molar heat capacity values for the metals in Figure 5.4. What observation can you make about these values—specifically, are they widely different or very similar? Using this information, estimate the specific heat capacity for silver. Compare this estimate with the correct value for silver, 0.236 J/g · K.

Interpretation Introduction

Interpretation:

The Specific heat capacity of silver has to be identified.

Concept Introduction:

The specific heat capacity (C) is the energy transferred as heat that is required to raise the temperature of 1gram of substance by one kelvin.

Explanation

Given the table for specific heat capacity (C) and atomic weights of metals
