No, lodestone, which is a form of the mineral magnetite, is denser than water so will not float. Its specific gravity is about 5.17.
No, carbon tetrachloride does not float on water because it is immiscible with, and heavier than water, and forms a lower layer.
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Objects float better in salt water because the denser the water the easier the object will float for instance if your at a salt water beach you will float easier in a salt water beach then you will floating in a swimming pool.
objects float better because chemicals help make the objects float higher. the more salt the higher the things go
no because it isn't hollow and denser than water
Tissue does not float in water. Tissue is denser than water, so it will sink when placed in water.
No, cashews are denser than water, so they generally sink in water rather than float.
Chloroform is denser than water, so it will sink in water.
Tar is denser than water, so it will sink in water.
No, peppercorns are denser than water so they will sink when placed in water.
Iodine is denser than water, so it will sink in a beaker of water rather than float.

Glycerin is denser than water, so it will sink when placed in water.
Potatoes are denser than water, so they sink when placed in water.
No, emeralds are denser than water, so they will sink to the bottom if placed in water.
Because some objects are a lot denser than water so the sink and others are less denser so they float
