When the computer receives a rich signal (high voltage) from the O2 sensor, it leans the fuel mixture to reduce the sensor's reading. When the O2 sensor reading goes lean (low voltage), the computer reverses again making the fuel mixture go rich.
Chemistry and physics are branches of science that both study matter. The difference between the two lies in their scope and approach. Chemists and physicists are trained differently, and they have different professional roles, even when working in a team.
I am supposed to do a paper on what chemistry is, and I am supposed to get different perspectives. I am a sophomore in HS, and have never had chemistry or chem.related classes before, so if you could make it kind of basic and easy to understand-that would be great! Heather Buchan.
