The alcohol is "oxidized" like any other fuel, producing water and carbon dioxide.
The reaction is C2H5OH + 3 O2 → 2 CO2 + 3 H2O + heat energy (from the CH bonds).
When fuels are burned, their chemical energy is converted into heat energy and light energy. Heat energy is released as a result of the combustion process, while light energy is produced in the form of flames or glowing embers.
Heat energy is released in a heat engine when fuel is burned. The heat energy is then changed into mechanical energy.

Empty calories. That's how you can get fat.
In a sense. Alcohol is metabolized into acetate by the liver, which is then burned for energy. However, it is burned in place of fat that would otherwise be metabolized. The fat is then stored (one cause of the famous "beer belly"). So, it does provide energy, but at the cost of screwing up your fat metabolism. Since the fat would have been burned in place of the acetate (were it not present) there is no real gain and considerable harm.
It is called stilling it is when alcohol is changed to ethanol by heating and cooling the alcohol
Most of the chemical energy from gasoline burned in a car is converted into heat rather than useful work. This heat is generated through the combustion process and is dissipated as waste energy through the exhaust system and the cooling system of the car.
When burned for energy,coal is a major pollutant.The reason coal is still burned to day is because it is a cheap source of energy as to solar or wind.
When fuels are burned, they contain chemical potential energy, which is converted into thermal energy (heat) and light energy (flame) during combustion. This process releases energy that can be harnessed for various purposes, such as generating electricity or powering vehicles.
The alcohol is the same. The production methods have changed. The biggest change was from beer and wine to distilled beverages.
