    Ignition
In summary, the ignition point of alcohol varies depending on its percentage and the presence of water. According to data, solutions with less than 20% ethanol will not ignite at room temperature, while solutions above 40 proof have a higher chance of igniting. The proof scale is based on the minimum flammable concentration at room temperature.

1. Can anyone explain in basic way, when alcohol begins to burn from external fire touch, precisely in procentage. as we kown vodka 40% of alcohol don't fire up.
2. Can anyone answer me in basic way, why is what ?

I don't get to understand what you want to know...

Sure it does, you just have to know how to ignite it.

I doubt you will get a single number as a lot depends on how you define ignition conditions.

It's depending of the % of water and the % of alchohol I think. :smile:

The concentration of ethanol in the water has to be high enough for its vapor pressure to be within flammability limits at that temperature. The vapor pressure does not increase linearly from zero to the value of pure ethanol when the alcohol percentage is increased, so it's difficult to calculate the minimum concentration without having experimental data, but the "proof" scale of alcohol percentage, where 100 proof is equal to 50% vol. of ethanol is based on the approximate minimum flammable concentration at room temperature.
 

1. What is the science behind alcohol ignition?

The science behind alcohol ignition involves understanding the chemical reactions that occur when alcohol is consumed and how it affects the body's ability to function properly. When alcohol is ingested, it enters the bloodstream and travels to the brain, where it slows down the communication between nerve cells and affects coordination, decision-making, and other cognitive functions. Additionally, alcohol can also impair the function of vital organs such as the liver and heart.

2. How does the percentage of alcohol affect ignition?

The percentage of alcohol in a drink directly affects the level of impairment it can cause. The higher the percentage of alcohol, the more it will slow down the brain's communication and impair cognitive and physical functions. This is why drinks with a higher percentage of alcohol are more likely to cause intoxication and increase the risk of accidents or injuries.

3. What is the legal limit for alcohol ignition?

The legal limit for alcohol ignition varies by country and state, but it is typically measured by the blood alcohol concentration (BAC) level. In the United States, the legal limit is 0.08% BAC for drivers over the age of 21. However, any amount of alcohol can impair a person's ability to drive safely, so it is always best to avoid driving after consuming any amount of alcohol.

4. How long does it take for alcohol to be eliminated from the body?

The average rate at which the body eliminates alcohol is about one standard drink per hour. However, this can vary depending on factors such as weight, gender, and the amount of food consumed. It is important to note that even after the effects of alcohol wear off, it can still be detected in the body for several hours.

5. Can drinking water or other fluids help prevent alcohol ignition?

No, drinking water or other fluids will not prevent alcohol ignition. The only way to prevent alcohol from affecting your body and brain is to avoid consuming it altogether. Drinking water or other fluids may help with dehydration, which can contribute to hangover symptoms, but it will not reduce the level of alcohol in the body or prevent its effects.
