A 25 gram piece of metal is sitting in a beaker of boiling water. The metal is taken out of the beaker and quickly placed in a calorimeter that contains 85 mL of water at 25.0 degree Celcius. After the metal released all of its heat the temperature of the water is 27.5 degrees Celcius.
What is the specific heat of the metal?

  1. heat = mass * specific heat * temperature change

    25 * x * (100. - 27.5) = 85 * 4.19 j/g⋅ºC * (27.5 - 25.0)
