Refer to Example 7-2. The experiment is repeated with several different metals substituting for the lead. The masses of metal and water and the initial temperatures of the metal and water are the same as in Figure 7-3. The final temperatures are 

(a) Zn, 38.9 °C;

(b) Pt, 28.8 °C; 

(c) Al, 52.7 °C. 

What is the specific heat capacity of each metal, expressed in J g^-1 °C^-1?

Example 7-2

Use data presented in Figure 7-3 to calculate the specific heat capacity of lead.
