Answer:
The level of the water will be higher for 100g Al because occupy more space than gold.
Explanation:
To understand this problem, we must know Archimedes' principle:
"A body that is submerged in a fluid produce a bouyant force equal to the weight of the fluid that the body displaces". The volume of the body is equal to the volume displaced in the liquid.
Now, as gold is heavier than aluminium, 100g of Al have more volume than 100g of gold, than means:
<h3>The level of the water will be higher for 100g Al because occupy more space than gold.</h3>
Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
