Specific heat of metal

        The purpose of this lab to identify the unknown metal by using specific heat of metal.
 Background:
        1calorie= the amount of heat needed to raise 1g H2O
          4.184 Joules=1calorie
           Food calorie =1Kcal or 1Cal
         q_w= m_wc_w(ΔT)w

 Specific heat.              J/g*c
             Water.                       4.184
              Al.                             .897
              Brass.                         .385
              Cu.                              .385
               Lead.                         .129
               Stainless steal.            .490
               Zn.                              .390

    Data:

Mass of metal:   70.512 g
Mass of water:114.991g
Temp of boiling water:99.7 C°
Temp calorimeter:20.2C°
Temp of calorimeter with hot metal : 24.4Co°
Temp change in calorimeter: 4.2C°
24.4-20.2=4.2C°
Temp change in metal sample: 75.3 C°
99.7-24.4=75.3C°
