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.
Best Answer: There are several differences between diesel fuel which is more like the vegetable oils that sometimes replace it and gasoline. Two significant differences are the flash point and the vapor pressure. The compressibility of the fuel before it will ignite is an entirely different question. Every liquid has a vapour pressure, which is a function of that liquid's temperature. As the temperature increases, the vapour pressure increases.
