Answer: An arc lamp is a lamp that produces light by an electric arc. Thecarbon arc light, which consists of an arc between carbonelectrodes in air, invented by Humphry Davy in the early 1800s, wasthe first practical electric light.
Answer: You can purchase dry ice (frozen CO2) from your local grocer for about $1.50 per pound.
Canisters of the compressed gas range in price, depending on the application. CO2 cartridges for air rifles may cost 50 cents each. Soda machine CO2 canisters have a wide range in price, as do the big compressed air bottles used by heavy industry.
Answer: semiconductors are silicon and germanium. they are like metals but their highest occupied electron shells/orbitals do not overlap. they require a little energy to exite electrons into the conduction band. Small amounts of group 3 or 5 elements can be changed to dramatically alter conductivity. the structure of carbon allotropes, such as diamond and graphite, do not allow this. Diamond is a covalent network with no free electrons. Graphite is layers of hexagonal carbon networks with electrons allowed to flow in one directing only. Adding these metal impurities, if it can be done easily, will not have the same effect
Answer: carbon pollution is people or objects putting a harmful chemical gas into the air-carbon. they can do this by- driving there car, using too much electrisity or spraying arocels in the air. this is also known as their carbon fottprint (how much carbon they leave behind)
Answer: The same hemoglobin molecules that absorb oxygen in the lungs release it to the cells in the capillaries and pick up carbon dioxide from the cells. When the blood returns to the lungs, the hemoglobin releases the carbon dioxide and replaces it with fresh oxygen. The carbon dioxide released by the hemoglobin travels across the membranes in the lungs and is breathe out when we exhale.
Answer: Carbon steel, also called plain carbon steel, is a malleable, iron-based metal containing carbon, small amounts of manganese, and other elements that are inherently present. Steels can either be cast to shape or wrought into various mill forms from which finished parts are formed, machined, forged, stamped, or otherwise shaped.
The carbon isotope Carbon-14, or radiocarbon, is found in the human body in the same proportions as there is carbon in the atmosphere. It comes to us from the food we eat, but the levels are too low to be dangerous, either to us or to the environment.
When something is burned (such as fuel, which contains carbon), a reaction takes place. Light, heat and physical force (in the case of an engine) are produced and oxygen is added. Recall that matter is not created nor destroyed, only converted. So when we add oxygen, it combines with the carbon to produce either carbon monoxide (one carbon one oxygen) or carbon dioxide (one carbon two oxygen).
Answer: not too sure what you want to know but i will explain the combustion process as best i can. gas car engines are a 4 stroke engine. the 4 strokes being: intake (down), compression (up), power (down), exhaust (up). engines operate off a reciprocating motion meaning the movement of one piston is the result of the opposite movement of a different piston. on the intake stroke the intake valve opens allowing fuel that has been mixed with air to be sucked into the cylinder by the downward travel of the piston (suction). on the compression stroke both the intake and exhaust valves are closed the piston travel back up with the air/fuel mixture in the cylinder. this compresses the air/fuel until he piston is at or near top dead center. then the spark from the spark plug ignites the air/fuel which causes a rapid expansion (not and explosion) or the air fuel thus pushing the piston down creating the power stroke. then the piston travels back up as the exhaust valve opens. the piston effectively pushes the spent air/fuel out of the cylinder. this is the basic principles of a internal combustion engine. now to more directly address your question. carbon monoxide is a by product of the air/fuel being burnt. the carbon monoxide (along with hydrocarbons and oxides of nitrogen) are pushed out on the exhaust stroke and into your exhaust system. it is the job of the catalytic converter to convert the carbon monoxide into carbon dioxide (a less harmful substance) it does this thanks to its chemical make up and elements that add an additional oxygen to monoxide to make it dioxide. its basically a filter for your exhaust.
