The heat flow , Q, due to temperature is found by the formula; Q = mC(Tf - Ti) Where m is the mass of the substance (50g), C is the heat capacity of the substance (C for water is 1cal/g-deg), and Tf & Ti are the final and initial temperatures of the substance (37 & 100). If the answer comes out negative the substance lost heat. If it comes out positive it gained heat.
