Question

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?

Answer 1

The melting point of gold is 1947.52 °F or 1337.33 K. To determine the kilocalories to raise its temperature, we need more information. The nugget's worth depends on its weight multiplied by the gold price per gram.

Step-by-step explanation:

The melting point of gold in degrees Fahrenheit is 1947.52 °F. In the Kelvin scale, gold melts at approximately 1337.33 K. For part C, we would need additional information as this requires knowledge of the specific heat of gold to determine the kilocalories needed to raise its temperature. However, assuming standard specific heat, you would need many kilocalories to raise the temperature of gold from 490.°C to 1064 °C. Lastly, for part D, the worth of the nugget in dollars would be dependent on its weight (in grams). Multiply the weight by the price of gold per gram ($42.16). For instance, if the nugget weighed 5 grams, it would be worth $210.80.
