The particles of which metal on heating to the boiling point of 357°C go from liquid state to gas state?

Mercury

The correct answer is option 1. Mercury.

The metal whose particles, upon heating to the boiling point of 357°C, go from the liquid state to the gas state is: Mercury

Mercury (Hg) is a metal that exists in liquid form at room temperature and pressure. Its boiling point is approximately 357°C (or 673 K). When heated to this temperature, the liquid mercury undergoes vaporization and transitions into the gaseous state. Therefore, option 1, Mercury, is the correct answer.
