Will Alcohol Left in a Car Spontaneously Combust in Summer?
1 Answers
Leaving alcohol in a car during summer can lead to spontaneous combustion, which is extremely dangerous. Here are relevant details about alcohol: 1. Ignition Point: Medical alcohol with a concentration of 75% has an ignition point of 20 degrees Celsius. During summer, outdoor temperatures at noon can exceed 40 degrees Celsius, and if a car is parked outdoors under direct sunlight, the interior temperature can reach over 50 degrees Celsius, making it highly susceptible to spontaneous combustion and explosion of alcohol. Alcohol left in a car under direct sunlight can explode. 2. Risk of Explosion: Alcohol is a flammable and explosive substance. In a sealed car compartment exposed to sunlight, temperatures can soar to 50-60 degrees Celsius. Without air circulation, encountering an open flame or flammable materials (such as a lit cigarette) can trigger an explosion. If stored in a glass container, sunlight can create a magnifying glass effect, focusing light and igniting the alcohol, which is highly likely to cause an explosion.
