Although anyone can become intoxicated while drinking, the alcoholic is less likely to recognize the signs and control his or her intake. Intoxication is produced by alcohol as it circulates in the blood and acts to depress the central nervous system (see depressant). Alcohol can pass directly into the bloodstream. The absorption rate depends principally on the concentration of the drug in the stomach and small intestine. This concentration is limited by the presence of alcohol dehydrogenase. Because women normally carry less alcohol dehydrogenase in their intestines, they usually consume less alcohol than men before showing its effects. Alcohol is not stored in the body or excreted but is metabolized in the liver at a fixed rate of between 0.25 and 0.33 oz (7.1-9.4 grams) per hour, varying with the individual. Thus alcohol is found in the bloodstream and signs of intoxication appear when the rate of alcohol consumption is greater than the rate at which it is metabolized in the liver. At a blood level of about .05%, alcohol impairs concentration, visual function, psychomotor performance, and reaction time. For many years the legal standard for drunkenness in most states was a blood alcohol level of .10%, but in many states it now is .08%. The lethal level, often given as .60%, may be as low as .40% in some people. Blood alcohol concentrations are measured by breath (the Breathalyzer test), blood, or urine tests.

Physical
Physical changes can include changes in size, shape, or state, while chemical changes involve the formation of new substances. Good effects of physical changes can include creating new materials like paper from wood pulp, while good effects of chemical changes include producing new medicines through chemical reactions. Both types of changes can be used to create new products and materials for various applications.
It will have no effect and cause no change.

no its a chemical change (i just did i project on making ice cream in meh class and one question was "is this a chemical or physical change? how do u know?"
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
