In an experiment, 426 g of water is in a copper calorimeter cupof mass 205 g. The cup and the water are at an initial temperatureof 10.9 oC. An unknown material with a mass of 361 g at atemperature of 296.1 oC is placed in the water. The system reachesthermal equilibrium at 36.1 oC. What is the specific heat of theunknown material? units = J/kg-C
