You are walking on a beach and find a mystery piece of metal. you take it back to your lab and measure its mass to be 0.5 kg. in order to heat the metal 1 degree k, you must add 115 j of heat. identify the metal. q =mcδt

For the given question above, I think there is a choice of answers accompanied with the question. Based on my research, the choices are:
A. Brass
B. Copper
C. Platinum
D. Silver

The answer for the question is option D. Silver.
Specific heat = 15 J / 0.5 kg
                     = 230 J kg-1

Substance                    Specific Heat (J kg-1 K-1)
   Aluminum                       900
   Copper                           390
   Brass                              380
   Silver                              230
   Platinum                         130

Yes
