Tar is less dense than saltwater, so it will float on the surface of saltwater.
Tar is denser than water, so it will sink in water.
Arsenic is denser than water, so it will sink in pure water.
An egg sinks in regular water because it is more dense than water. When salt is added to water, it increases the water's density, making the egg less dense than the saltwater and causing it to float.
The grape will initially float due to its density being lower than that of the saltwater. However, as the grape absorbs the saltwater through osmosis, it will start to sink as its density increases. Ultimately, the grape will end up fully submerged in the saltwater.
Plutonium is a dense metal and will sink in water due to its high density.
Tar is denser than water, so it will sink in water.
It will float for a while than slowly sink because its density as a cube is Heavier than water (by the way waters density is 0.9-1.0 g and Tar is 1.02 g). I hereby conclude with all reasons that tar ( in a shape of a cube) will float then sink
No all tar does float. For something to float then it must be less dense than saltwater.
Amber floats in saltwater due to its low density. It is often used as a test for authentic amber since imitations or fakes will sink in saltwater.
Rubber typically floats in saltwater due to its low density. The buoyant force acting on the rubber is greater than its weight, causing it to float.
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
The property that causes an object to float in saltwater but sink in freshwater is density. Saltwater is denser than freshwater due to the dissolved salts, so objects that are less dense than saltwater will float in it but sink in freshwater.
Saltwater is denser than freshwater, so when you add salt to water, the water becomes more dense. When you place an egg in saltwater, it floats because the density of the saltwater is higher than the density of the egg, causing it to float instead of sink.

it will float as long as it is not fully covered water.
