Final answer:
The boiling temperature of gold, 2966 °C, is converted to Kelvin by adding 273.15, resulting in 3239.15 K.
Step-by-step explanation:
To convert the boiling temperature of gold from Celsius to Kelvin, we can use the direct conversion formula:
TK = °C + 273.15
By plugging in the boiling temperature of gold, which is 2966 °C, into the formula:
K = 2966 °C + 273.15 = 3239.15 K
Therefore, the boiling temperature of gold in Kelvin is 3239.15 K, which corresponds to option (a).
