Which of the following is closest to the boiling point of platinum?

• A. 3140 °C
• B. 1768 °C
• C. 3825 °C
• D. 2500 °C

Answer: (C)

Verified step by step guidance

1. Understand that the boiling point of an element is the temperature at which it changes from liquid to gas under standard atmospheric pressure.
2. Recall or look up the known physical properties of platinum, specifically its boiling point, from a reliable source such as a chemistry reference table or database.
3. Compare the given options (3140 °C, 1768 °C, 3825 °C, 2500 °C) to the known boiling point of platinum to identify which value is closest.
4. Note that platinum is a transition metal with a very high boiling point, typically much higher than many common metals, so expect the correct answer to be the highest value among the options.
5. Confirm that the boiling point of platinum is approximately 3825 °C, making that the closest and correct choice.
