An unknown metal has a mass of 86.0 g. When 2330 J of heat are added to the sample, the sample temperature changes by 60.4 "C. Calculate the specific heat of the unknown metal. What is the possible identity of the metal based on the calculated specific heat? () tin () gold () iron () nickel Metal Specific heat (J/g -~ C) iron 0.449 tin 0.210 gold 0.129 barium 0.204 calcium 0.650 nickel 0.440 Calculate the final temperature after 80.9 g of a metal alloy (c = 0.513 J/g.C) at 89.8 .C is placed in 175 g of water at 15.2 .C. Assume no heat is lost to the surroundings. Tfinal = .C
