An electric range burner weighing 614 grams is turned off after reaching a temperature of 499.0oC, and is allowed to cool down to 22.2oC.

Calculate the specific heat of the burner if all the heat evolved from the burner is used to heat 565 grams of water from 22.2oC to 80.9oC.

  • chemistry - ,

    [mass burner x specific heat burner x (Tfinal-Tinitial)] + [mass H2O x speific heat H2O x (Tfinal-Tinitial)] = 0

    Substitute and solve for specific heat burner which is the only unknown in the equation..
