No. If you heat liquid alcohol enough it will evaporate and you will have alcohol vapor, but its still alcohol. Making it a physical change. If you expose alcohol to a flame and burn it, that will change the alcohol into carbon dioxide and water, then it's a chemical change.
When alcohol is heated, it evaporates at a lower temperature than water. This means that when alcohol is heated, it will turn into vapor more quickly than water.
1. Never heat alcohol directly on naked flame 2. you should take a beaker with boiled water in it and then place the alcohol with the test tube in it 3. you should wear goggles while heating alcohol. 4. never smell the alcohol directly after heating
When alcohol is oxidized it becomes acetaldehyde, which is toxic. The acetaldehyde quickly become acetate, and then finally carbon dioxide and water.
Alcohol is not heated in the starch test because heating can denature the enzymes involved in the reaction, leading to inaccurate results. The purpose of the starch test is to detect the presence of starch by forming a blue-black color complex with iodine, which does not require heating.
Yes, alcohol readily changes to a gas (vapour) at room temperature.
Physically or chemically.

Apprently, there is no free carbon in alcohol.

It is called stilling it is when alcohol is changed to ethanol by heating and cooling the alcohol
