Tumbleweed Whenever you think of the Wild West of America, you think of cowboy movies and tumbleweed, perpetually tumbling around a desolate landscape. According to the American movies, tumbleweed is as American as apple pie.
3 Answers. , I am a serious student of all questions relating to the environment. Gasoline can be ignited by even a tiny spark at temperatures as low as fifty below zero, but it merely evaporates at temperatures up to about four hundred seventy five to five hundred F. At that temperature, it ignites spontaneously.
Too Hot to Handle. The peak flame temperature of ethanol is 1,920 degrees Celsius (3,488 degrees Fahrenheit), while the peak flame temperature of methanol is 1,870 degrees Celsius (3,398 degrees Fahrenheit). Ethanol also has a higher flash point than methanol: about at 14 degrees Celsius (57.2 degrees Fahrenheit) to methanol's 11-degree Celsius (51.8 degrees Fahrenheit) flash point. A volatile liquid's flash point is the lowest temperature at which it can vaporize to form an ignitable mixture in the area.
