Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic

Dissolved oxygen enters water through the air and plant. Dissolved oxygen produce by the atmosphere and the process is called air saturation. The gasses a stable body of water with no stratification‚ dissolved oxygen will remain at 100% air saturation. 100% air saturation means that the water is holding as many dissolved gas molecules as it can in equilibrium. At equilibrium‚ the percentage of each gas in the water would be equivalent to the percentage of that gas in the atmosphere like its partial

Why Oxygen is Important Oxygen plays a vital role in the treatment of patients. Oxygen is the molecule that helps the cells in our body produce ATP through a process known as cellular respiration. Also it is the number one drug of choice for the American heart association. Finally it is a priority according to the universal care protocols in the protocol book given to flight medics in USAAAD at Fort Polk. In short Oxygen is important for the medics to use. To start off with oxygen helps sustain

There are many ways that I have been illiterate in my life. One way that I think has had the biggest impact in my life was not having the “normal” family that most kids seem to have growing up. I never had the family where the mom bakes all the time and takes her kids to soccer practice and drives a mini van‚ while the dad doesn’t come home until later at night just to help his kids with their homework and tells them goodnight while him and his wife talk about their day apart. Instead‚ I was the

I was about 10 minutes circling to find a parking nearby‚ until I saw a married couple with two children walking toward a car. I stood behind them driving too slow‚ I went along to their

REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added

Oxygen Cycle Required for Life All living things use oxygen or depend on organisms that use oxygen in some way. All Animals and Other Consumers Use Oxygen We use oxygen to break down simple sugar and release energy. This can be done through respiration or fermentation. Animals mainly use respiration.

Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the
