An object with a specific gravity (SG) of 7.5 which could be a mixture of something with a SG higher than 7.5 and something with a lower SG.
Yes, sand is generally heavier than Styrofoam. Sand has a much higher density, meaning it is more compact and contains more mass in a given volume compared to Styrofoam, which is a lightweight material made from expanded polystyrene. Consequently, if you compare equal volumes of both materials, sand will weigh significantly more than Styrofoam.
A high specific gravity means a substance is denser compared to water. It is a measure of how much heavier a substance is compared to an equal volume of water.
1The mL and the cm3 are equal volumes.
If we have equal volumes of gold and bismuth, then the gold would be heavier than the bismuth. The specific gravity of gold is 19.29 whereas the specific gravity of bismuth is 9.79.
A gallon of fresh water is heavier than a gallon of sea water because fresh water is denser than sea water.
Compared to a low density substance and all other things being equal, it would be heavier.
Liquids are generally heavier than solids because the molecules in liquids are more densely packed together and have more mass per unit volume compared to solids. Additionally, liquids tend to have a higher density than solids, making them heavier when compared in equal volumes.
Not necessarily. Equal volumes do not always mean equal masses because different substances have different densities. Denser substances will have more mass in a given volume compared to less dense substances.
The answer depends on what the numbers measure. If they are the masses of equal volumes of substances, then the substance with mass 0.8 is denser. On the other hand, if the numbers refer to the volumes of equal masses of two substances, then the substance with volume 0.7 is denser.
No, it depends on the specific gravity (or relative density) of the substance. E. g. Compare the weighs of 1 cubic metres of cork and iron.

The resulting volume of a sugar mixture is generally equal to the sum of the volumes of the individual components. When sugar is mixed with another substance, the total volume will be close to the sum of the volumes of the two separate components.
Yes. Ice expands when it freezes. So equal volumes would weigh different amounts, with the ice weighing less.
A gallon of fresh water is heavier than a gallon of sea water because fresh water is denser than sea water.
The substance with a density of 2.1 g/cm3 will sink in water, as it is denser than water (density of 1.0 g/cm3). This means that the substance will not float but will sink to the bottom of the container filled with water.
