Which element of the boron family has a high boiling point, making it ideal for recording temperatures that would vaporise a thermometer?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Gallium.
Gallium is the element of the boron family that has a high boiling point, making it suitable for recording temperatures that would vaporize a thermometer. Gallium has a boiling point of approximately 2204°C (3999°F), which is high enough for it to be used in high-temperature thermometers. This property allows it to remain in liquid form over a wide temperature range, making it useful for accurate temperature measurement in various industrial applications.
