a microphone in which a diaphragm, vibrated by sound waves, applies a varying pressure to a container packed with carbon granules, altering the resistance of the carbon. A current flowing through the carbon is thus modulated at the frequency of the sound waves
- Carbon monoxide hemoglobin
carbon monoxide hemoglobin carbon monoxide hemoglobin n. See carboxyhemoglobin.
a colorless, odorless, poisonous gas, CO, that burns with a pale-blue flame, produced when carbon burns with insufficient air: used chiefly in organic synthesis, metallurgy, and in the preparation of metal carbonyls, as nickel carbonyl. Contemporary Examples For example, research has shown that most carbon-monoxide alarm incidents are triggered by a malfunctioning furnace. How to […]
- Carbon monoxide poisoning
carbon monoxide poisoning carbon monoxide poisoning n. A potentially fatal condition caused by inhalation of carbon monoxide gas which competes favorably with oxygen for binding with hemoglobin and thus interferes with the transportation of oxygen and carbon dioxide by the blood. Also called carboxyhemoglobinemia. Historical Examples And if you don’t get it, you’ll press a […]
