Final answer:
The flash point of diesel is above 100 °F not exceeding 200 °F, while the flash point of gasoline is below 73 °F.
Step-by-step explanation:
The flash point of diesel and gasoline refers to the minimum temperature at which they can produce enough vapor to ignite.
Diesel has a higher flash point than gasoline. Diesel has a flash point of above 100 °F not exceeding 200 °F, meaning it requires a higher temperature to ignite compared to gasoline. Gasoline, on the other hand, has a flash point of below 73 °F, indicating it can ignite at a lower temperature.
It is important to note that the flash point alone does not determine the fire hazards of a substance. Other factors like volatility and the presence of ignition sources also play a role.
