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.
What else can I help you with?
Is alcohol evaporates physical or chemical changes?
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.
Is the smell of alcohol a physical change?
The smell of alcohol is not a physical change; rather, it is the result of the volatile compounds in alcohol evaporating into the air. When alcohol evaporates, it changes from a liquid to a gas, which can be detected by our sense of smell. This process is a physical change, as it involves a change in state without altering the chemical composition of the alcohol itself.
Are the changes produced by electrolysis chemical or physical in nature?
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.
Can mixtures be separated by physical change?
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.
Do chemical equations show summaries of physical change?
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.
What produced the physical and mental changes by drinking alcohol?
Intoxication
how internal bleeding can be prevented?
Physical therapy and lifestyle changes,such as quitting smoking or drinking alcohol
After drinking alcohol what changes occur in the body?
After drinking alcohol the following changes occur in the body; * vision becomes blurred * reactions become slower * body begins to produce vomit.
What qualitative evidence is there that a person has been drinking?
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.

What three things does drinking provoke?
Drinking alcohol can provoke altered states of consciousness, impairment of cognitive functions, and changes in behavior.

Is sugar that changes into alcohol a chemical or physical property?
It is a chemical change
What type of changes occurs in thermal expansion and contraction?
These are physical changes. No new substance is produced.
Is the sun's energy is produced by physical and chemical changes in the interior?
False
Explain Why physical changes can be reversed but chemical changes cannot?
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.
