Gold, one of the most sought-after metals in the world, has a density of 19.3 g/cm3, a melting point of 1064 ∘C, and a specific heat of 0.129 J/g ∘C. A gold nugget found in Alaska in 1998 weighed 16.37 lb. A kilogram of 7.44 Part A: What is the melting point of gold in degrees Fahrenheit?

Part B: What is the melting point of gold in kelvins?

Part C: How many kilocalories are required to raise the temperature of the nugget from 490. ∘C to 1064 ∘C?

Part D: If the price of gold is $ 42.16 per gram, what is the nugget worth in dollars?
