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?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
