Once the alcohol goes into our system, an ounce of it is process for a period of one hour. 
The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.
Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
 
        
             
        
        
        
Answer:
Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.
Explanation:
For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.
When you put water onto water, it's an addition of water, you don't say it's wet or wetter.
Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.
Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.
So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
