Sometimes, water can become overheated, like if it is near a factory or power plant. If the water's temperature increases, then the Dissolved Oxygen (DO) level will decrease, which can cause strain or even death for many fish and marine wildlife.

If you poor the water slowly when no oxygen can escape into the container make less of a chance of getting oxygen into the water.

What is dissolve oxygen?

Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.


What is biological oxygen demand?

It determines the amount of dissolved oxygen that is consumed by aerobic biological microorganisms in water. It is measured by the amount of oxygen that is consumed per liter of sample during 5 days of incubation it is in milligrams.


Where would you expect to find the largest amounts of dissolved oxygen in the ocean water?

Oxygen best dissolves at surfaces. So generally, you would find the largest amount of dissolved water at the surface, which is in contact with the air. As for a region, I would assume a region that has a lot of photosynthetic organisms and not a lot of oxygen consumers. Another factor that should be kept in mind, is that the lower the concentration of solutes (i.e.. salt) in the water, the more oxygen can be dissolved. For example, at 10 degrees Celsius, up to 8.02mL of oxygen can be present per liter of freshwater, but only 6.75mL of oxygen is dissolved per liter of saltwater. ______________ In polar regions. In polar regions


What is the effect of temperature on the amount of oxygen that water a different temperatures can hold?

As a gas, its solubility in water decreases as temperature increases.Boiling water produces oxygen gas bubbles, which means you can get out most of the oxygen dissolved in water by boiling water, thus, for example, a fish can't live in water you boiled.


Does water have oxygen in it?

Oxygen is an element which exists as a diatomic gas at room temperature. Water is a compound of oxygen and hydrogen at two parts to one. Water may also contain dissolved oxygen. The atmosphere contains about 20% oxygen, and may also contain water vapour. Short answer: no, oxygen does not contain water.

how does temperature affect the concentration of dissolved oxygen?

Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.

Which contain the greater amount of dissolved oxygen a lake in the spring or a lake in the summer?

. Temperature directly affects the solubility of oxygen in water. When the temperature of water increases, a portion of oxygen converts from liquid state to a gas. Thus the ability of water to maintain oxygen in dissolved state decreases with increasing temperature. As a result, colder water can potentially contain more dissolved oxygen than warm water. Therefore, a lake in spring contains greater amount of Dissolved Oxygen than the same lake in summer.
