Q (water) = 4.186

Unknown #: III

H = q

q= mass x specific heat (cs) x change in Tempature (t)

Cs = q/ m*t

After calculating specific heat go to the table to see what's close to your answer

Specific Heat Values of Common Metals:
Iron 0.444 J/g ◦C
Lead 0.129 J/g ◦C
Aluminum 0.890 J/g ◦C
Nickel 0.444 J/g ◦C
Zinc 0.388 J/g ◦C
Copper 0.385 J/g ◦C

Water Data:

Mass of calorimeter (mass of 1 styrofoam cup): 12.5 g

Mass of calorimeter + water: 27.67 g

Mass of water: 15.17 g

The initial temperature of water: 22°C

The final temperature of water: 99.5°C
