A 26.0 g sample of polyisoprene, which has a specific heat capacity of 1.880 J-g¹.C-1, is dropped into an insulated container containing 250.0 g of water at 65.0 °C and a constant pressure of 1 atm. The initial temperature of the polyisoprene is 4.4 °C. Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has 3 significant digits.
