Nope; specific gravity is lower
Salt
yes chalk is denser then water.
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
It is better to use the muddy puddle water than the seawater because of the salt
Antifreeze, Pesticide then Gasoline. Antifreeze has to weigh right at as much as water to make sure they mix in the cooling system - no bubbling up. Pesticides are made from materials lighter than water but mixed with water as a medium, so they are lighter than antifreeze. Gasoline is very light (the lighter the fuel with the same energy content, the more efficient it is), it' lighter than water so it's definitely lighter than antifreeze. Since pesticides are mostly water, in all likelihood gasoline is lighter than the pesticides.antifreeze > pesticides > gasoline
Salt
Cold freshwater is generally denser than warm seawater. As water cools, it becomes denser until it reaches about 4°C; below this temperature, it begins to expand and lose density. In contrast, seawater, while denser than freshwater due to its salt content, is typically warmer and less dense than cold freshwater. Therefore, cold freshwater is denser than warm seawater.
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
Seawater is denser than freshwater because it contains salt. The salt in seawater increases the mass of the water without significantly increasing its volume, making it denser. Temperature and pressure can also affect the density of seawater.
the salt makes seawater denser than freshwater. more salt increases the density
Seawater becomes more dense when the temperature decreases or when salinity increases. Cold water is denser than warm water, and water with higher salt content is denser than water with lower salt content.
Seawater because it contains salt which makes the water more dense than water which does not contain salt.
sea water is less denser than river water.
Gasoline is less denser than milk.
Much more dense. They are the two lightest gasses in the universe, and gasoline is a liquid, which is always denser than a gas.
Motor oil will float on water. That makes water denser.
