A hot solid substance with mass 3.44kg and temperature 81.5 oC, is taken out of the oven and placed in cool liquid water of mass 2.04kg and temperature 20 oC. Heat flows from the hot substance to the water until they are both at the equilibrium temperature of 31.8 oC. Assuming no heat transfer between the environment and the water/substance system, find the specific heat of the substance. Take the specific heat of water as 4190 Jkg -1C -1. Express your answer to at least 3 significant figures in Jkg -1C -1
