Oxygen is one of the gases that humans use daily. It is necessary to support life itself. Other common gases used on a daily basis include carbon dioxide and methane.
All animals require oxygen. Most remove oxygen from the air through the lungs, although fish use their gills to remove dissolved oxygen from water. In animals, cells that do not receive oxygen die.
Oxygen is also required for combustion. Homes that burn fuel for heat require oxygen to support the flame. Every time the gasoline engine of a car starts, it uses oxygen that combines with the fuel to produce power.
Carbon dioxide is one of the waste gases that results from respiration in animals. It is required for plants to produce glucose for energy. Since carbon dioxide does not support combustion, fire extinguishers use the compressed gas to stop fires. Pressurized carbon dioxide, found in cans of soda, causes the bubbles in soft drinks.
Methane is a simple hydrocarbon consisting of one carbon atom and four hydrogen atoms. Methane is the primary ingredient of natural gas that many homes use for heat. Methane forms from the breakdown of plant and animal waste. Such breakdowns occur in swamps and manure heaps. Methane is a greenhouse gas that, along with carbon dioxide, contributes to climate change.Learn More
Bromine is used in everyday products such as pesticides and water treatment solutions. Bromine is a reddish-brown gas that has a pungent smell and can irritate the skin, nose and eyes. Bromine was discovered in 1826 by A.J. Balard.Full Answer >
A pressurized water reactor uses a nuclear reaction to heat water. It then transfers that heat to a steam generator to drive an electric turbine. These reactors use two completely separate water loops to ensure no radioactive water or steam escapes the system. After the steam drives the turbine, it is condensed and flows back into the system, cooling the water in the primary loop, which then cools the reactor.Full Answer >
Lemonade is a mixture because sugar, water and lemons are combined together without a chemical reaction taking place. The bonds of the substances can't combine with one another, instead the three items are mixed up.Full Answer >
