What else can I help you with?
What is the approximate oxygen content of air?
The approximate oxygen content of air is around 21%.
What is the solubility of oxygen in water exposed to air at 1 ATM and 298 K?
This solubility is 8 mg/L.
What evidence did you observe that oxygen is not very soluble in water?
Oxygen's low solubility in water is evidenced by the fact that oxygen concentrations in water are relatively low compared to other gases like nitrogen. Additionally, the solubility of oxygen decreases as water temperature increases, further indicating its limited solubility. Lastly, the need for aquatic organisms to extract oxygen from the surrounding water or through specialized structures like gills highlights the challenge posed by oxygen's low solubility in water.
What is the boiling point of oxygen in Celsius at 1atm of pressure?
The boiling point of oxygen at atmospheric pressure (1 atm) is -183 degrees Celsius.
How do you know oxygen is slightly soluble in water?
Oxygen dissolving in water is a well-documented phenomenon observed in laboratories and natural environments. This solubility is driven by the partial pressure of oxygen in the air and is essential for aquatic life to survive. Numerous studies have quantified the concentration of dissolved oxygen in water, establishing its solubility characteristics.
What is the solubility of oxygen in fresh water at a temperature of 5 degrees?
The solubility of oxygen in fresh water at 5 degrees Celsius is approximately 14.6 mg/L. As water temperature decreases, the solubility of oxygen increases because colder water can hold more dissolved oxygen.
Does oxygen have solubility?
yes it does
What is the relationship between temperature and oxygen solubility in water?
The relationship between temperature and oxygen solubility in water is inverse. As temperature increases, the solubility of oxygen in water decreases. This means that colder water can hold more dissolved oxygen than warmer water.
How does the solubility of oxygen in water change with temperature?
The solubility of oxygen in water decreases as temperature increases. This means that warmer water can hold less oxygen compared to colder water.
What happens to the solubility of oxygen in a pond as the pond decreases temperature?
As the pond decreases in temperature, the solubility of oxygen increases. This is because cold water can hold more dissolved gases than warm water. This can benefit aquatic organisms, as they rely on dissolved oxygen for survival.
What is the approximate oxygen content of air?
The approximate oxygen content of air is around 21%.
Is temperature inversely proportional to concentration of oxygen?
No, temperature and concentration of oxygen are not inversely proportional. Changes in temperature can affect the solubility of oxygen in water, but the relationship is not strictly inverse. The solubility of oxygen generally decreases with increasing temperature.
What is the solubility of oxygen in water exposed to air at 1 ATM and 298 K?
This solubility is 8 mg/L.
What is oxygen's state at 1000 degrees Celsius?
At 1000 degrees Celsius, oxygen exists in a gaseous state. Oxygen gas (O2) is a colorless and odorless gas at this temperature.
What state of matter is Oxygen at -250 degrees Celsius?
Oxygen at -250 degrees Celsius would be a solid.
Is oxygen a gas at negative 250 degree Celsius?
Yes, oxygen is still a gas at negative 250 degrees Celsius. Oxygen has a boiling point of -183 degrees Celsius, so it would be a gas at -250 degrees Celsius.
What is state of oxygen at negative 50 degrees Celsius?
At -50 degrees Celsius, oxygen would be in a gaseous state. Oxygen condenses into a liquid state at temperatures below -183 degrees Celsius.
