Does mercury substance has weight?

The density of mercury is 13,534 g/cm3.


Why is it inaccurate to say heavy objects sink and light objects float?

Because it is all about the physical concept of Density . You should say that an object will float if it's Density is lower than the Density of the fluid you choose to put it into . Example. Aluminum will float in Mercury liquid, because it is less dense than Mercury, yet you might refer to Aluminum as a heavy object , depending upon what other substance you are comparing it to.

Would a block of aluminum float or sink in a pool of mercury at room temperature with a density of 13.6?

A block of aluminum will float on a pool of mercury at nearly any temperature (except at extremely elevated temperatures (above 350 °C) where mercury is no longer liquid) The density of aluminum is 2.70 grams per cm3, whereas the density of mercury is 13.53 grams per cm3. Therefore mercury is more than 5 time more dense than aluminum! Anything that is less dense than a liquid will float in that liquid. Not only would aluminum float but it float with only 1/5 of it's volume submerged.


Which substance has the highest density at room temperature out of water hydrogen and oxygen?

mercury


What is the most dense liquid substance?

Mercury, with a density of 13.590 Kg/m3


What is lightest mercury or aluminum?

Aluminum is the lighter than mercury.


Will aluminum sink or float in mercury?

Aluminium will always float in Mercury. The mass of the Aluminium is irrelevent. If you think of a more common example does it matter how big the piece of wood is as to whether it floats in water? Aluminium floats in Mercury because it is lighter than the same voluime of Mercury just as wood floats on water because it is lighter than same volume of water.


Will a solid piece of iron float in a sample of mercury?

Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.


What is mercury relative density?

The specific gravity of Mercury is 13.56. The density of mercury is 13.534 grams per cubic centimeter. Density is usually the ratio to the density of a given reference material.
