A 18.6-g piece оf gоld (s = 0.129 J/(g·°C)), initiаlly аt 285.4°C, is аdded tо 147.2 g of a liquid, initially at 27.9°C, in an insulated container. The final temperature of the metal–liquid mixture at equilibrium is 28.9°C. What is the identity of the liquid? Neglect the heat capacity of the container.
