Which metal has less specific gravity?
Specific gravity is highest in rocks rich in iron, magnesium oxide, and the heavy metals and lowest in those rich in alkalies, silica, and water.
Which among these has least specific gravity?
Hence, from the reported values of the specific density gold has the highest specific density, and marble has the lowest specific density among the given options. Hence, the correct answer is C.
What mineral has the least specific gravity?
ice
Osmium has the highest Specific Gravity among minerals approved by the IMA, ice has the lowest.
Which metal has highest specific gravity?
Amongst metals, lead has the highest specific gravity, that is, it has the highest density in comparison to water at any specific temperature. This is closely followed by the metal gold when it comes to the specific gravity.
Does metals generally have a low specific gravity?
False. Metals generally have a very high specific gravity. Metals like iron, lead, mercury, gold etc. have specific gravity values greater than 7.5. However, sodium and potassium are the only metals with a specific gravity value below 1.
Do metals have high specific gravity?
All metals are hard and strong. Mercury and gallium are metals which exist in liquid state at room temperature. Most of the metals have high specific gravities.
Which metal has least relative density?
The first chemical element with the lowest density is Hydrogen and the highest density is Osmium. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
What is specific gravity of aluminum?
2.7
Weight. The specific gravity of aluminium is 2.7, about one-third that of iron (7.9) and copper (8.9).
Which metal does not corrode in air?
The metal that does no corrode in air is aluminium. Al is that metal which don’t corrode in air.
What is the example of soft metal?
According to the Mohs hardness scale, a list of soft metals includes lead, gold, silver, tin, zinc, aluminum, thorium, copper, brass and bronze. Gallium might also be considered a soft metal, as it melts at 85.57 degrees Fahrenheit. Mercury is a metal that’s liquid at room temperature.
Does gold have a high specific gravity?
It is common to use the density of water at 4 oC (39 oF) as reference – at this point the density of water is at the highest….
