Miners discover a new vein of metal in the mine they are excavating. They send a sample to your lab so you can
determine what type of metal it is. You heat up a 2 kg block of the unknown metal from room temperature of 298 K
until it melts at 1768 K. You measure that it takes 1.24 x 10^6 J of energy to melt the block. Use the specific heats of
various metals shown below to determine what metal the miners have discovered.
Aluminum: 904 J kg-1 K-1
Nickel: 445 J kg-1 K-1
Copper: 384 J kg-1 K-1
Cobalt: 421 J kg-1 K-1
Titanium: 520 J kg-1 K-1
