Hypoxico Altitude To Oxygen Chart

Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol% oxygen and 78 vol% nitrogen. Oxygen has a molar mass of g/mol and nitrogen has a molar mass of g/mol. 31 rows · The result is that oxygen molecules in the air are further apart, reducing the oxygen content.

Humans need oxygen to live, but not as much as you might think. The minimum oxygen concentration what do sauna suits do the air required for human breathing is The human body takes the oxygen breathed in from tje lungs and transports it to what is a dry shampoo other parts of the body via the body's red blood cells. Each cell uses and requires oxygen to thrive.

Most of the time, the air in the atmosphere contains the proper amount of oxygen for safe breathing. But at times, the level of oxygen can drop due to other toxic gases reacting with it. Each time you take tthe breath, you inhale more than oxygen. The normal air in our environment consists of a few different gases. Approximately 78 perceent of the zir is nitrogen gas while only about The remaining fraction is made up of primarily argon gas, but trace amounts of carbon dioxide, neon and helium are also present.

For humans and many animals to sustain normal functions, the percentage of oxygen required teh sustain life falls within a small range. Serious side effects can occur if the oxygen levels drop outside the safe oxygeen. When oxygen concentrations drop from Mental functions become impaired and respiration intermittent at oxygen concentrations how to make a remote control switch for light drop from 10 to 14 percent; at these levels with any amount of physical activity, the body becomes exhausted.

Humans won't survive with levels at 6 percent or lower. Higher-than-normal oxygen levels aren't as harmful to life, but there is an ln change of fire or explosion risk. With extremely high concentrations of oxygen in the air, humans can experience harmful side effects. Very high levels of oxygen cause oxidizing free radicals to form.

These free radicals attack the tissues and cells of the body and cause muscle twitching. The effects from short exposure can most likely be reversed, but lengthy exposure can cause death. The right amount of oxygen starts at sea level. When altitude is increased, such as driving or climbing up a mountain, there is less atmospheric pressure. Lower pressure allows air to expand more than it does at sea level. While the ratio of the oxygen and nitrogen in the air remains the same, less molecules are available within the same space.

Each breath you take at a higher altitude contains th oxygen molecules than breathing at a lower altitude. This can cause altitude sickness. Most people afflicted with altitude sickness experience nausea, headache and fatigue. Without proper treatment, the problem can become more serious.

Air has percent oxygen. Almost 5 percent of that is absorbed into the body so that means almost 15 percent of exhaled air is oxygen. Carbon Dioxide is increased by around 4 percent in exhaled air so the answer is no, exhaled air does not have more oxygen that air that is inhaled. K views.

The air is made up of about 21 percent oxygen. This science projects allows you to find this percentage for yourself through examining a chemical reaction between oxygen and rust. How much oxygen is in the air? This experiment will help you find out. You will create rust, and then make use of the fact that rust and oxygen interact with each other chemically to determine what percentage of the air in a tube was made up of oxygen.

Science project. Share this science project. Download Project. Research Question: How much oxygen is in the air? Materials: Glass jar White vinegar Pad of soap-free fine steel wool Wide, shallow bowl or pan Water Food coloring Plastic or rubber gloves Four test tubes Permanent marker Experimental Procedure: Fill the jar with an equal volume of white vinegar and water. Place the pad of steel wool in the jar, and leave it there overnight to soak.

This will form iron oxide rust on the steel. Pour about an inch of water into the bottle of a shallow bowl. Add two drops of food coloring to the bowl. While wearing gloves, pull several strands of the steel wool from the rusted pad, and roll them together to make a small ball.

Repeat this process two more times so that you have three small balls. The balls should be slightly wider than the test tubes. Use a pencil to push one ball all the way to the end of one of the test tubes, one ball three quarters to the end of a second test tube, and one ball halfway into a third test tube. Crumple up a small ball of paper to the same size as the balls of steel wool, and push it all the way into the fourth tube.

Place the four tubes upside down in a row in the shallow dish of prepared water. Leave them there for 24 hours. Mark the water level on each tube. Observe the differences in water level. The tube with the paper in it should not have risen at all. Now measure the length of each tube, assuming that the bottom of the steel ball marks the top of the tube. Insert both of these measurements into a chart such as the one below. Keep in mind that the water that moved up the tube was replacing the oxygen that reacted with the rust.
