The combustion of ethanol occurs when there is a reaction of ethanol with oxygen. There is a significant release of energy while this reaction is occurring.
For ethanol and oxygen to experience combustion, the temperatures have to be at a high level. When reacting with oxygen, the products are water and carbon dioxide. During combustion, scientists observe the ethanol flame being nonluminous and pale blue in color. Scientists may use ethanol to increase the temperature of water. When looking at 90 grams of water, ethanol is able to take the temperature of 68 degrees Fahrenheit and take it up to 212 F as long as all of the heat focuses on the water.
