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.
@sanchises: Gasoline is easier to ignite than diesel or kerosene. The reason spark-ignited engine can only run on gasoline is that the spark would not ignite the heavier fuel at all or it would burn too slowly. In the compression-ignition engine the temperature is much higher so it ignites even diesel.
