Water or bubble which is denser, water or salt water which is denser

Theoretically, the density of water should be greater than that of foam, there are many cavities in ordinary foam, all of which are gases, and the density of gas is generally much lower than that of water. If you are talking about soap foam or detergent foam, it is composed of some gas bubbles wrapped in a solution, and as long as the bubbles do not burst, they are less dense than water and float on the surface of the water.

The density of liquids and solids is related to their respective properties, and there is no absolute difference in size.

For example, water is denser than ice, and mercury is liquid at room temperature, but it is larger than many metals and heavier than many liquids and solids at room temperature.

At the same air pressure, the density of the liquid state of a general substance is less than that of the solid state. The exception is water, which is highest at 4 degrees Celsius at the same air pressure. The density of ice is less than that of water, which is why ice is restored to the surface of the water.

The density of plastic and resin is less than that of water, and foam plastic is a plastic mixed with air, which is less dense and will not sink in water.

Rubber is denser than water, and it will sink if it is not mixed with air. When a certain proportion of air is mixed in, that is, when the density of the foamed rubber is less than that of water, it will float on the water.

As for the detailed explanation of the principle, you will know it when you understand Archimedes' law.

In general, water is dense.

Most of the solids are denser than the liquids.

But there are exceptions: water is denser than ice, mercury is denser than many solids, and pumice is less dense than many liquids (because of the void space inside pumice).

Of course, it is water, take a volume of soaking and water, and the water must be heavier than soaking.

Even if there is no air in itPlastic is as dense as water.

It must be that the density of water is high, and the density of solids is not necessarily greater than that of liquids, for example, the density of mercury is greater than that of wood.

The density of solid foam is greater than that of water, but that means compressed, and there are many cavities in the foam, so the density of water should be greater than that of foam.

What do you think of bubbles? They are all the same substance, should be the same, the density is equal to m v, and it is generally divided into solids, liquids, and gases. Liquids and solids can be put together, and then judged according to the principle of buoyancy, in general, the density of gases is the smallest.

The density of a solid is not necessarily greater than that of a liquid.

The density of ice is the density of water.

The density of wood and the density of water.

Not necessarily. Ice is not as dense as water.

Why not take a look at it for a while? Aren't leaves and duckweed solid?

Another: The foam you asked about is polyurethane foam rubber, which will not sink when it just falls into the water, and will sink after the small gap in the middle is filled with water.

For example, wood is less dense than water.

Salt water. Saline is a solution that consists of a solvent (water) and a solute (salt). The weight of the brine is equal to the sum of the two before, and the volume is equal to the volume of the solvent, so naturally the brine is larger.

The density of salt water is high. The density of salt water is higher than that of water. The density of water is 1 g cm, and the density of salt water is greater than 1 g cm.

The density of saline depends on the concentration of the solution, and the density of saturated table brine is. When there is dust or dirt in the home, splash some salt water on the dirty area to achieve the effect of sterilization, the principle is to use the osmotic pressure of salt water to make bacteria lose moisture.

Hello dear, the density of salt is relatively large.

The density of water is high! Water is a liquid, and liquids are denser than gases!

When you talk about vapor here, you should mean water vapor! Water vapor is also a gas and is less dense than water!

The density of water is 1000 kilograms per m, and most people have a slightly greater density than water, about 1000 or more, and some people have a smaller density, so in general it should be a little more dense than people.

The density of the human body is slightly greater than that of water.

Water is denser than air, and bubbles rise in the water!

The formation process of urine with higher urine density than water: when the blood flows through the glomeruli, the uric acid, urea, water, inorganic salts and grape slow-mixed sugar and other substances in the blood are filtered into the renal sac through the filtration of the inner wall of the glomeruli and the renal sac, forming protourine. When urine flows through the renal tubules, all of the glucose, most of the water, and some or more inorganic salts in the original urine are reabsorbed by the renal tubules and returned to the blood in the capillaries around the renal tubules.

Urine is formed by the reabsorption of raw urine by the renal tubules, and the remaining water, inorganic salts, urea, and uric acid. The human body forms about 150 liters of raw urine every day, but very little urine is actually excreted.

The blood is circulating, which means that the same drop of water in the blood passes through the kidneys many times a day to become raw urine.

The 180 liters he said are also repeated, and you're constantly producing raw urine, and you're constantly being reabsorbed by the renal tubules, so that all you add up to 180 liters in a day

Which white manuscript is said to produce 180L per day.。。。 Only about 60% of a normal person's body is water, are you sure that you are filial piety? The density of urine is greater than that of water.

This refers to the accumulation of raw urine produced every day, and by the time the next liter is produced, this liter has been reabsorbed into the bloodstream and circulated throughout the body.

The density of water and oil is that water is denser and denser.

According to the exact data: the density of water is density: 1g cm3. Edible oil is roughly in; The density of volatile oils is mostly between. It can be seen that the density of water is high.

In daily life, for example, when drinking soup, you will find oil floating on top of the water, which can also indicate that the density of water is greater than that of oil.

Water is denser than oil.

The density of water is density: 1g cm3.

Edible oil is roughly in; The density of volatile oils is mostly between.

From daily life, it can be observed that oil is always floating on the surface of the water, which directly proves that water is denser than oil.

The density of water is: three. The oil is: cubic.

Water,,, oil and water are put together, and the oil floats on it.
