Which element has the highest boiling point?
-
Diamond
-
Platinum
-
Tantalum
-
Titanium
C
Correct answer
Explanation
Tantalum has the highest boiling point (approximately 5,458°C or 9,856°F) among the given options. This refractory metal is extremely heat-resistant, making it valuable for high-temperature applications like jet engine components and nuclear reactors. Diamond is not an element but pure carbon, platinum melts at a lower temperature, and titanium also has a lower boiling point.
