How do I find heat flow??? I've looked all over the internet and my book and there isn't a single formula called "heat flow." Can someone show me how to find it?

More information about the experiment: We heated metal in a test tube, then added it to room temperature water in a calorimeter. The start temperature of the metal was right after it was heated, the start temperature of the water was before the metal was added, and the temperature change reflects the results of adding the metal to the water. The identity of the metal is unkown.

Explanation / Answer

The heated metal was in high temperature compared to the water present in the calorimeter. When you added the metal in the waterthere will be exchange of heat and a thermal equilibrium will be reached. heated metal will released some amount of heat (heat flow metal to water) and water will absorbed some heat (heat flow to the water from the metal).

Heat flow to water = mass * specific heat * temp difference

                           = 40 g * 4.184 J oC-1 g-1* (24.8-22.6)

                           = 368.19 J

Heat flow of metal = - [mass * specific heat of the metal * temp difference]

                           = -[16.09 * S* (96.5-24.8) ]

Heat flow of water = heat flow of metal

From there specific heat of the metal can be calculated.
