mercury is a better barometric fluid than water because i. it needs no colouring ii. its density is many times greater than that of water iii. it does not wet glass iv. it has a high vapour pressure v. it has a high boiling point. which of the above statements are true?

that is very wrong..one is dat mercury has very low vapour pressure compared to water..

I still think the answer should be B..because mercury is shiny hence needs no coloring for its opacity and again...

Being to an advantage to the user for taking more accurate readings,it really does not wet glass

The correct statements are:

i. **It needs no colouring**: True. Mercury is easily visible due to its distinctive silvery color.

ii. **Its density is many times greater than that of water**: True. The density of mercury is approximately 13.6 times that of water, which allows for a shorter column in barometers.

iii. **It does not wet glass**: True. Mercury does not adhere to the glass in a barometer, providing more accurate readings.

iv. **It has a high vapour pressure**: False. Mercury actually has a low vapour pressure, which is beneficial because it minimizes errors due to evaporation.

v. **It has a high boiling point**: False. Mercury has a lower boiling point than water. However, its boiling point is still sufficiently high (356.73°C) that it remains in a liquid state under normal atmospheric conditions.

So, the correct answer is i, ii, and iii.

Mercury is a coloured liquid metsl which needs no additional colouring.
Mercury does not wet glass but water does.
