It is assumed that the heat given up by the metal is transferred to the water. The specific heat of water is 4.18 J/g°C, which means that 4.18 Joules of heat energy is required to raise the temperature of 1 gram of water 1 °C. Use the table below to determine which metal your unknown is.

Metal	Specific Heat (J/g°C)
Aluminum	0.902
Brass	0.380
Copper	0.385
Gold	0.126
Iron	0.449
Nickel	0.444
Silver	0.235

Fill out the table below and determine the identity of the unknown metal.
