The density of air decreases as the bubble rises, since the bubble can increase in size as it rises. A Scuba diver needs to release air from her lungs when rising from a depth for this reason. The density of air inside a Japanese fishing net float (a hollow glass sphere) would not change substantially. Changing its temperature would not change the density, only the pressure, since the same number of molecules are involved.

What is the connection between density and salinity?
I think that as the salinity increases, density increses. The minerals that contribute to the salinity of sater, such as sodium and chloride, are denser that water. Thus, when the dense particles are added, the density of the water increases I think that as the salinity increases, density increses. The minerals that contribute to the salinity of sater, such as sodium and chloride, are denser that water. Thus, when the dense particles are added, the density of the water increases
What is the SG of water?
The specific gravity (SG) of water is a dimensionless quantity that is defined as the ratio of the density of water to the density of a reference substance, typically water itself at 4°C, where it has its maximum density of approximately 1,000 kg/m³. Therefore, the specific gravity of water is 1.0. This means that water has the same density as itself, which serves as the baseline for comparing the densities of other substances.
How to calculate mass of water from density?
You have to use the density equation... D = M / V D= density M= mass V= volume You have to find the volume of your water. Since you know your density the only thing left to find out is the mass. Just solve for it by multiplying the volume times the density.
What is a comparison of density to the density of an equal volume of water?
Density is defined as mass per unit volume, and when comparing the density of a substance to that of an equal volume of water, we typically use water as a reference point, with a density of approximately 1 gram per cubic centimeter (g/cm³) at standard temperature and pressure. If a substance has a density greater than 1 g/cm³, it will sink in water, while a substance with a density less than 1 g/cm³ will float. This comparison is crucial in various applications, such as buoyancy calculations and material selection in engineering.
Does salt water stay a top fresh water?
No, it will be at the bottom - difference in density.
Why does an air bubble rise to the surface of a glass water?
An air bubble rises to the surface of water due to buoyancy. The density of air is lower than the density of water, causing the air bubble to experience an upward force that makes it float towards the surface. This is also known as the principle of Archimedes.
Why does water bubble up?
Water bubbles up when heated because the heat causes the water molecules to move faster, which decreases their density. As the density of the heated water decreases, it rises to the surface and forms bubbles.
What is it called when an air bubble rises to the surface of water?
Buoyancy.
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.
Why an air bubble in water burst as it emerges on water surface?
An air bubble in water bursts at the surface due to a decrease in surface tension. As the bubble rises, the water surrounding it is dragged along, stretching and thinning the surface layer. When the bubble reaches the surface, this thin layer breaks, causing the bubble to burst.
What causes a bubble to float in water?
Its average density is a lot less than water
When liquid water is warm its density?
decreases as it becomes less dense and expands. This is why warm water rises in cooler water.
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
When an air bubble rises in water what happens to its potential energy?
no matter what happens to the bubble, even if it sinks or rises, the mass will remain the same throughout. we all know that as we go deeper into water, the pressure increases with the depth. hence, when the bubble rises, the pressure exerted on it decreases and simultaneously, the volume increases. that is all that happens to the bubble. the mass remains constant unless it bursts. the mass of air in the bubble originally is now dissolved in the water. always remember that the mass of anything is constant as long as it is acted upon the same gravitational force.
Does your density change when you are in water?
No, your density does not change when you are in water. Your density is determined by your mass and volume, and it remains constant regardless of the medium you are in.
How does air bubble inside the water behave and why?
When an air bubble is released underwater, it will rise to the surface due to buoyancy. Buoyancy is the upward force exerted by a liquid on an object immersed in it. As the air bubble rises, the water pressure decreases and the bubble expands in size until it reaches the surface.
What happens to a sample water when it is heated between 4c and 100c?
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
