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 4.2 g . She then finds that upon absorption of 50.8 J of heat, the temperature of the rock rises from 25 ∘C to 55 ∘C. Find the specific heat capacity of the substance composing the rock. Determine whether the value is consistent with the rock being pure gold.

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 4.7 g. She then finds that upon absorption of 52.7 J of heat, the temperature of the rock rises from 25 ∘C to 57 ∘C. Find the specific heat capacity of the substance composing the rock. Express the specific heat capacity in joules per gram-Celsius to two decimal places....

5. 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 5.2 g. She then finds that upon absorptions of 59.3 J of heat, the temperature of the rock rises from 23 °C to 59 °C. Find the specific heat of the object and determine if it matches the specific heat of real gold. (c = 0.128 J/g°C)
