Does the density of the air in a bubble change as a bubble rises in water?

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.

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.
Does salt water stay a top fresh water?
No, it will be at the bottom - difference in density.
Example of sentence density current?
And example of a sentence using the term density current might be this one: The water in the north was much colder than the basin water, and this colder water, because it was more dense than the seawater in the basin, created a density current that caused the cold water to flow into the lower area of the basin.
What is the relationship between density and temperature?
Due to thermal expansion, as temperature increases, density decreases.There is no simple relationship. Usually, but not always, if a substance is heated, it will expand, thus decreasing its density.
Why does an air bubble rise to the surface of a glass water?
The deeper you go under water the higher the pressure due to the weight of water above. Therefore the pressure of the water at the level of the bottom of the bubble is higher than the pressure at the level of the top of the bubble. The unbalanced force forces the bubble up. In all mixtures of (non-reacting) fluids and gases, the higher the density of a component, the lower it lies. Anything that has a density less than 1g/cm cubed (water density) floats but if it has a higher density than water then it sinks.
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?
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
Does a substance change density if it changes physically?
Depends on what you consider a physical change. Substances change their density when they change their state of matter. When the temperature rises, substances usually expand, wich leads to the density decreasing. When the temperature falls, substances contract, increasing the density. Exception would be water, as it shows an anomaly occurring near 273K
What happen to gas bubble volume as they rise in water?
As a bubble rises to the surface of a liquid the pressure on it is going DOWN. Therefore the bubble expands, and usually bursts at the surface.
What causes a bubble to float in water?
Its average density is a lot less than water
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
What is the volume of a bubble?
It depends on the size of the balloon. As the diameter of the balloon increases, its volume is cubed, therefore the volume quickly increases with the size of the balloon.
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.
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
Does the density of water depend on the temperature of water?
Most definitely yes. Water has its maximum density at 4° C. By definition this is the point at which clean water has a density of 1 exactly. It gradually becomes less dense as its temperature rises. When it changes state for liquid to gas, it undergoes a tremendous change in density, dropping to 0.0006 at 100° C. When it freezes, it also undergoes a big change in density, but not as drastic. It drops to 0.9150 at 0° C. Since it is less dense than liquid water, ice floats.
Does the volume of water change the density of water?
Density = mass / volume. So if the volume changes, the density will obviously also change.
