Suppose you have an open topped box that is 5cm x 5cm x 5cm. (capacity: 125 cubic centimetres)
Inside the box is a steel ball-bearing that is 25 cubic centimetres in size.
Next to the box is a two litre pail filled with mercury.
How many cubic centimetres of mercury would you have to pour into the box to completely submerge the ball bearing?
__________
Mercury is denser than steel and the ball would float atop the liquid metal.
That depends...Quote:

This question is not one where we can ask for clues, sorry bro.
volume is 25cm cubed so the radius is 1.8cm (diameter 2.9cm therefore the vloume of mercury required to submerge the bearing would be 5X5X2.9 - 25 = 72.5 cm cubed. although mercury should be refered to in mL not centimeters, and like 3fs said, assuming the ball bearing has a greated density than mercury.
Psst.
That was RIOT, not 3fingersalute. ;)
my bad
Alright then, the ball bearing will float in the mercury and therefore, can never be covered.Quote:

Hey technical objection :p - I knew for sure that steel was less dense than mercury & wouldn't have had to try for clues ('cos he got one despite your objection) one quick squizz at the periodic table on the back of my 'junior chemist' ruler told me all I needed to know.. :DQuote:

I believe your geekhood is therefore to be 'truely' repected :devil:
Actually, I was betting on it being a trick question. It seemed like too much math to work through, so the correct answer had to be simpler... :thumbs:Quote:

I do indicate when questions are of the "ask a clue" variety. They're usually worht much more at the start though.
No harm done... :pQuote:

I still don't now why mercury is called hg though :D, even if I do accept that it was always going to be a trick question ;)
It is a symbol based on the Latin: hydrar***** (liquid silver).
Google is still allowed for non-MindTrap questions. :D
Now he tells us... :flame:Quote:

And a bonus for coming up with a valid explanation which was different from the official one.
