Yes. Alcohol enters the blood stream within 40 seconds to a couple of minutes after being drunk. Two hours can see quite a reduction in levels as long as you haven't had anything to drink within those two hours.
80 hours after the alcohol has been metabolized by the body.
The body metabolizes alcohol at the rate of approximately 1/3 ounce of pure alcohol per hour. Nothing can be done to speed that up. If you chug one ounce of 190 proof (and are able to keep it down) it will take three hours to clear it from your body; six hours for two ounces, etc. This translates to about two 12-0z. beers in three hours.

It will typically take between 4 and 24 hours for 1.5 ounces of alcohol to get out of your system. The actual amount of time depends on body chemistry and the metabolism.
Alcohol will remain in the body anywhere from 1 to 6 hours depending on the amount of alcohol ingested. Alcohol metabolizes at a rate of 0.15 BAC per hour.

A breath alcohol test measures the amount of alcohol in your body by measuring the amount of alcohol in the air that you exhale. The test can be administered by a a device that is electronic or manual.
The amount of alcohol that has been consumed and the time elapsed since the last alcohol consumption.
Probably not. What the breath test is measuring is the amount of ETOH that is in the breath of a specific volume of air. The body metabolizes alcohol at different rates based on each person but approximately .015 BAC is metabolized out of the body each hour. Therefore in 48 hours after drinking it is unlikely that any alcohol would be detectable. You'd likely be blowing 0s.
Alcohol will start leaving your body in an increasing speed until it reaches a peak (in about 30 minutes) in which it will leave your body in a constant speed. So the days it will take deppend on the amount of alcohol you took. It could be in less than 24 hours, and it is generally. Now, the persistance of the effects deppend on the damage the alcohol caused to your body.
