Part A To determine whether a shiny gold-colored rock is actually gold, a chemistry student decides to measure its heat capacity. She first weighs the rock and finds it has a mass of 4.9 g. She then finds that upon absorption of 54.6 J of heat, the temperature of the rock rises from 25 °C to 58 C. Find the specific heat capacity of the substance composing the rock. Express the specific heat in joules per gram-Celsius to two significant...
