gold is heavier than aluminium if we put a 100 gram biscuit of gold in water taken in a measuring cylinder or we put a 100 gram aluminium bar in the measuring cylinder will the rise in the level of the water be same or different in the two cases give reason

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:

gas
