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

One reaction

In our chosen chemical reaction we decided to do Calcium metal and water. We put water in a test tube and after that we dropped few pieces of Calcium metal. When we added Calcium metal to water we witnessed water started boiling and making white foam bubbles and hydrogen gas smoke.         H20+Ca=Ca(OH)2+H2
