Why would oxygen diffuse much faster in air than water?
Oxygen diffuses faster in air than in water because air has lower density and viscosity compared to water. This results in less resistance to the movement of oxygen molecules, allowing them to travel more quickly through the air compared to water. Additionally, the concentration of oxygen in air is higher than in water, further facilitating the diffusion process.
Why might stream water have more oxygen in it than pond water does?
Stream water typically has more oxygen because it flows constantly, allowing more oxygen from the air to dissolve into the water. In contrast, pond water is stagnant and can become depleted in oxygen over time due to limited exchange with the atmosphere.
Does still water have more oxygen than flowing water?
Flowing water generally has more dissolved oxygen than still water because moving water allows more oxygen to be absorbed from the air. Still water can become depleted of oxygen over time due to lack of replenishment, especially in stagnant or enclosed areas.
Why air dissolved in water contains maximum percent of oxygen?
Air dissolved in water contains a higher percentage of oxygen than nitrogen because oxygen is more soluble in water than nitrogen. This is due to the differences in their molecular characteristics, such as molecular weight and polarity, which affect their solubility in water.
How do you dissolve oxygen in water?
By bubbling oxygen (or air) through the water, splashing water through the air (waterfall). That is where the oxygen that fish breathe comes from. It is separate from the oxygen that was chemically combined with hydrogen to form the water.
Is oxygen in water better than oxygen in the air?
Oxygen in water and oxygen in the air have different levels of availability for organisms to use. Oxygen in water is more readily available to aquatic organisms since it dissolves in water more easily. However, terrestrial organisms, like humans, primarily rely on oxygen in the air for respiration.
Does air and water give any difference effect on oxygen level?
Yes it does as a matter of fact, if the water has a high mass there will be less air causing less oxygen whereas if the water has a low mass there will be room for more air so more oxygen hope that helped!
How much air is in hot water Is there more air in cold water under the same pressure of course?
Colder water can hold more oxygen than warmer water.
Why air is a better respiratory medium?
the respiratory medium of aquatic and terrestrial organisms are water and air respectively.Aquatic animals get oxygen dissolved in water while terrestrial animals get oxygen from atmospheric air.The oxygen content of air is much higher then the oxygen content of water.The ventilation in water is far more difficult than the ventilation in air because water is denser then air. Thus air is the better respiratory medium then water.
What is the advantage of air as respiratory medium?
the respiratory medium of aquatic and terrestrial organisms are water and air respectively.Aquatic animals get oxygen dissolved in water while terrestrial animals get oxygen from atmospheric air.The oxygen content of air is much higher then the oxygen content of water.The ventilation in water is far more difficult than the ventilation in air because water is denser then air.

Why whale dive out of water?
To breath more freely in open air. Percentage of oxygen in water is less for big creatures like whale. Therefore, sometimes they come out of water for more oxygen.
How does splashing in a waterfall change the water?
The splashing exposes more water surface to the air, allowing it to absorb more oxygen. Good news for the fish. It also encourages evaporation of the water into the air.
Why does a river with rapids contain more dissolved oxygen?
The more water moves the more it has a big surface of contact with the air with is rich in oxygen and therefore oxygenates the water. Also the movement makes that the deeper waters have a chance to get to the surface, exposing to the air part of water that would not be exposed otherwise.
Is water in the oxygen you breathe?
What we breathe is air, and oxygen is just 20% of the air. Oxygen does not contain water, it is an element and it contains only itself. However, air does contain some water vapor.
