Oxygen dissolves in water through a process called diffusion, where oxygen molecules move from an area of high concentration to an area of low concentration. Factors that influence this process include temperature (higher temperatures decrease oxygen solubility), pressure (higher pressure increases oxygen solubility), and the presence of other substances in the water (such as pollutants or salts).

How does oxygen dissolve in water and what factors influence this process?
Oxygen dissolves in water through a process called diffusion, where oxygen molecules move from an area of high concentration to an area of low concentration. Factors that influence this process include temperature, pressure, and the presence of other substances in the water.
What is oxygen in water called?
Oxygen dissolved in water is typically referred to as dissolved oxygen (DO). The amount of dissolved oxygen is crucial for the survival of aquatic organisms and is influenced by factors such as temperature, pressure, and biological activity.
Can oxygen dissolve?
Yes. Fish survive by "breathing" the oxygen dissolved in the water.
How hot does oxygen burn and what are the factors that influence its combustion temperature?
Oxygen itself does not burn, but it supports combustion. The temperature at which oxygen supports combustion varies depending on the material burning. Factors that influence combustion temperature include the type of material, the amount of oxygen present, and the efficiency of the combustion process.
How does steel wool burn and what are the factors that influence its combustion process?
Steel wool burns when exposed to a flame due to its high iron content. Factors that influence its combustion process include the presence of oxygen, the temperature of the flame, and the thickness of the steel wool.

How long does it take for amber to form and what factors influence the process?
Amber forms over millions of years from the fossilized resin of ancient trees. Factors like temperature, pressure, and the presence of oxygen can influence the process of amber formation.

Steel wool burns when exposed to a flame due to its high iron content. Factors that influence its combustion process include the presence of oxygen, the temperature of the flame, and the thickness of the steel wool.
What changes the amount of dissolved oxygen in the water?
Factors such as temperature, pressure, salinity, and the presence of organisms can affect the amount of dissolved oxygen in water. For example, higher temperatures typically result in lower dissolved oxygen levels, while photosynthesis by aquatic plants can increase dissolved oxygen through oxygen production.
What do you call process the process when oxygen can be dissolved in water?
The process of oxygen dissolving in water is called "oxygenation." This occurs when oxygen molecules interact and become dispersed within the water molecules resulting in oxygen being absorbed by the water. It is essential for aquatic life and is influenced by factors such as temperature and pressure.
What are the Physical and biological factors affecting the solubility of dissolved gases in aquatic ecosystems?
Physical factors affecting the solubility of dissolved gases in aquatic ecosystems include temperature (lower temperature increases gas solubility) and pressure (higher pressure increases gas solubility). Biological factors include photosynthesis (increases oxygen levels) and respiration (decreases oxygen levels), as well as microbial activity and nutrient levels that can influence gas solubility.
How might you account for dissolved oxygen concentrations of such a low value at a temperature of 25C?
Low dissolved oxygen concentrations at 25°C could be due to factors like high water temperatures, which reduce the amount of oxygen that can remain dissolved in water. Additionally, high organic matter levels or excessive algal blooms can result in increased oxygen demand, lowering the dissolved oxygen concentration. Poor water circulation or a lack of aeration can also contribute to low oxygen levels.
What is dissolve oxygen?
Dissolved oxygen refers to the amount of oxygen present in water. It is essential for aquatic life to breathe and thrive. Factors such as temperature, water flow, and levels of organic matter can impact the amount of dissolved oxygen in water.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
