Obvious symptoms of Alcoholism include slurred speech, dilated pupils, shaking hands or other extremities, and being constantly off-balance. Some of the lesser obvious symptoms of an alcohol problem include the unusual or unexplained need for money, injuries which the person won't or cannot explain, and unexplained change in personality and attitude.
Evaporation is a physical change- it is still alcohol. The change can be undone by colling the air and condensing the ethyl alcohol vapor back to liquid alcohol.
The changes produced by electrolysis are chemical in nature. The process involves the conversion of electrical energy into chemical energy, resulting in the decomposition of compounds into their constituent elements or ions.
Some mixtures can be separated by physical changes. For example distilling alcohol can be done by heating the mixture to between the boiling points of water and alcohol, so the alcohol boils off, leaving the water. The alcohol is then condensed into another container.
Chemical equations show the identities of the substances involved in a chemical reaction and the ratios in which they react or are produced. They do not provide a summary of physical changes such as changes in state or appearance. Physical changes involve alterations in the physical properties of a substance without changing its composition.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Intoxication
Physical therapy and lifestyle changes,such as quitting smoking or drinking alcohol
After drinking alcohol the following changes occur in the body; * vision becomes blurred * reactions become slower * body begins to produce vomit.

Qualitative evidence that someone has been drinking may include the smell of alcohol on their breath or clothes, changes in behavior such as slurred speech or unsteady movements, and physical signs like red eyes or flushed skin. Other signs could be empty alcohol containers nearby or the person admitting to drinking.

Drinking alcohol can provoke altered states of consciousness, impairment of cognitive functions, and changes in behavior.

It is a chemical change
These are physical changes. No new substance is produced.
False
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
