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
