What happens to an objects density when it obsorbs water?
If the object's original density is less than water (sponge, for example) - the density will increase. If the object's original density is greater than that of water (though I cannot think of anything that fits that category that is porous enough to absorb water), the density will decrease.
When a submarine pumps water out of its inflation tanks its density decreases and floats.why does its density decrease?
It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.
How does heat affect the density of water?
As water is heated, its density decreases. When water molecules are heated, they gain energy and move around more, causing the molecules to spread out and the water to expand. This expansion leads to a decrease in density.
How does temperature change the density in water?
As temperature increases, water molecules gain energy and move faster, causing them to spread out and increase in volume, resulting in a decrease in density. Conversely, as temperature decreases, water molecules slow down and come closer together, leading to a decrease in volume and an increase in density.
When air bubbles rises in water its volume increases what happens to its mass and density?
The mass of the air bubbles remains the same as they rise in water, but their density decreases. This is because as the volume of the air bubbles increases, they displace more water, causing their density to decrease relative to the surrounding water.
What causes the decrease in the density of warming water?
The decrease in the density of warming water is mainly caused by thermal expansion, which occurs when water heats up and molecules spread apart, making water less dense. Additionally, melting ice caps can contribute to a decrease in the density of water as fresh water mixes with seawater, further lowering its density.
What can causes an increase in the density of the ocean water?
salt a decrease in temperature and an increasue in salinity
Does cold air increase or decrease water density?
Cold air decreases water density because colder temperatures cause water molecules to move closer together, resulting in increased density. Conversely, warm air causes water molecules to expand and move farther apart, leading to decreased water density.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
When a submarine pumps water out of its floating tanks its density decrease and it floats why does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
Does evaporation of salt water causes density to increase or decrease?
It causes the density to increase because the more salt added to water, the more buoyant or dense it becomes. Salt itself does not evaporate as the water does so as the water evaporates the salt content is effectively increased, therefore making the water more saline or dense.
What causes to be more water?
Global Warming causes there to be more water in the world.If that is what your asking....
Do evaporation of salt water cause density to increase or decrease?
The density of water increase after evaporation.
When liquid water freezes into ice its density .?
Decreases
Does evaporation of saltwater cause density to increase or decrease?
The density of the water increases.
Does evaporation of salt water cause it to increase or decrease density?
The density increase after evaporation.
What causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
