The particles of which metal on heating to the boiling point of 357°C go from liquid
state to gas state?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Mercury.
- Heating a liquid mercury to its boiling point of 357oC, and under the right pressure conditions, all particles in the liquid state go into the gas state.
- Mercury is an anomaly and the only metal that is liquid at room temperature.
- Mercury also has an ability to stick to itself (surface tension) – a property all liquids exhibit.
- Mercury has a relatively high surface tension, which makes it very unique.
