Which is the flash point of gasoline?

The flash point of gasoline is indeed around -43°C (-45°F). The flash point is the temperature at which a liquid produces enough vapor to ignite in the presence of an ignition source. Gasoline is a highly volatile liquid, and its low flash point indicates that it can easily ignite at relatively low temperatures. This characteristic is significant for fire fighters as it poses a substantial hazard when handling or responding to gasoline fires. Understanding the flash point helps in assessing the risks associated with gasoline and implementing proper safety measures when dealing with this flammable liquid.

In contrast, the other choices represent temperatures that are higher than the actual flash point of gasoline, making them unsuitable options. Knowing the correct flash point is essential for fire safety and effective firefighting strategies.
