Specific Heat of a Sample of Water


“Water has the same number of vibrational modes as a crystal with the same number of atoms. Calculate the specific heat of 1 mol of water.”


This SWBQ is a good exercise to see if students can effectively use the internal energy to find the specific heat of a material at room temperature. The answer to this problem will also give the common value seen for the specific heat of water at room temperature. Students must first be shown the equipartition theorem for solids.
