What is the flashpoint range of automatic transmission fluid?

The flashpoint of a substance is the minimum temperature at which it can vaporize to form an ignitable mixture in air. Automatic transmission fluid (ATF) generally has a flashpoint that falls within the range of 302-536°F, which is why this answer is correct.

This temperature range is important because it indicates the point at which the fluid can become a fire hazard. Understanding the flashpoint is critical for fire investigators and safety professionals, as it helps in assessing the risks associated with different fluids during a fire incident.

The other ranges provided do not align with the typical properties of automatic transmission fluid. The choice of 250-350°F is considered too low for ATF, while 400-500°F is above the acceptable range, and 275-325°F does not accurately reflect the commonly documented flashpoints for this fluid. Thus, recognizing that ATF has a flashpoint starting at 302°F justifies why the chosen option is the most accurate representation of ATF's properties.
