Brewing, Distilling and Denaturing: Test Your Alcohol Knowledge
How much alcohol can your body eliminate in one hour?
As a rule of thumb, the average person can eliminate 0.5 ounces (15 milliliters) of alcohol per hour. So, it would take approximately one hour to eliminate the alcohol from a 12-ounce (355-milliliter) can of beer.
Which is not a property of alcohol?
Alcohol is less dense than water and evaporates at a lower temperature, which allows it to be distilled.
What type of alcohol do people consume?
The type of alcohol found in alcoholic beverages is ethyl alcohol (or ethanol), made up of carbon, hydrogen and oxygen.
Which beverage contains the most ethyl alcohol?
Champagne usually contains 12 percent ethyl alcohol, while beer has 4.5 percent and wine has 11 percent.
At what blood alcohol concentration level (BAC) can a person fall into a coma?
At 0.35 to 0.5 percent BAC, a person may become unconscious and their heart rate could slow, possibly leading to coma or even death.
Which part of the brain does alcohol affect first?
Alcohol affects various portions of the brain, beginning with the cerebral cortex. The cerebral cortex manages perception, judgment and speech. As the BAC increases, more areas of the brain are affected.
When affected by alcohol, which area of the brain causes fuzzy memories and exaggerated emotions?
The brain's limbic system, which controls emotions and memory, consists of structures like the hippocampus and septal area. As alcohol affects this system, the drinker is subject to exaggerated states of emotion, like anger, aggressiveness, withdrawal and memory loss.
Which of these is a popular misconception about alcohol?
Although alcohol increases blood flow toward the skin and may momentarily give you a warming sensation, it actually causes you to lose body heat.
What percentage of Americans over the age of 18 suffer from alcoholism?
In the United States, approximately 8 percent of people ages 18 and older suffer from alcohol abuse and/or dependency. This abuse or dependency costs about $1.7 billion in medical treatment, lost earnings, casualty damages and criminal/legal costs.
Which is not an effect of long-term alcohol use?
Sperm production in males actually decreases because of the decreased sex-hormone secretions from the hypothalamus and pituitary glands and, possibly, the direct effect of alcohol on the testes.
What percentage of alcohol absorbed by the bloodstream is eliminated by the lungs?
The lungs exhale 5 percent of alcohol. This can be detected by a breathalyzer.
How does alcohol affect sexual performance?
As your blood alcohol concentration level increases, sexual behavior increases, but sexual performance declines.
What causes a person under the influence of alcohol to sweat or appear flushed?
Alcohol increases the blood flow to the skin. This causes sweating and a drop in body heat.
Alcohol dissolves in the water inside each tissue in the body except for:
Alcohol cannot dissolve in fat tissue.
Where in the human body does the breakdown of ethanol occur?
The oxidation, or breakdown, of ethanol occurs in the liver by an enzyme called alcohol dehydrogenase.
Which of the following describes what happens when your body becomes more tolerant to alcohol?
When the body becomes more tolerant to alcohol the body increases the liver’s enzymes, which break the alcohol down faster. The body also increases brain activity.
During a performance test, you are asked to bring your finger to your nose with your eyes closed. If you are unable to perform this action, what part of the brain is affected?
The cerebellum controls fine movements, so if it's not functioning properly, the smooth motion of bringing your finger to your nose would be shaky or jerky.
What three variables affect the absorption rate of alcohol?
Alcohol absorption depends upon the following things: concentration of alcohol in the beverage, the level of carbonation in the beverage and the amount of food in your stomach.
At what blood alcohol concentration level (BAC) can a person die?
A person can die with a BAC over .50 percent.
Alcohol can be made by three methods. Which of the following is NOT one of them?
The chemical combination of oxygen and carbon monoxide produces carbon dioxide, not alcohol. Alcohol can be made by fermentation, fossil fuels and the combination of hydrogen and carbon monoxide.
Booze, hooch, devil's brew. Whatever name you call it, alcohol is really just a combination of carbon, hydrogen and oxygen molecules. Test your knowledge of this simple compound with our quiz!
