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.Know More
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 about Chemistry
Oxygen is the gas that has eight protons and eight neutrons. Oxygen also has eight electrons and an atomic number of eight. The melting point of the element is -218.79 degrees Celsius, and the boiling point is -182.95 degrees Celsius.Full Answer >
Oxygen is one of the primary components that allows air to be breathable to people and it began forming in the atmosphere approximately one billion years ago. Until the ozone layer formed, most life on the planet was restricted to the oceans.Full Answer >
Gases and liquids are considered fluids because they both flow and move. The molecules comprising both gases and fluids are constantly in motion in random formations. The molecules continuously collide with each other and the sides of any container in which they are placed.Full Answer >
The primary difference between liquids and gases is that the constituent molecules of liquids are closer together and move less than those that make up gases. Liquids and gases behave in a number of similar ways, although both differ greatly from solids.Full Answer >
