- Aniline point
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Fuel properties are defined by various temperature points.
We need to identify the lowest temperature at which fuel ceases to flow.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the definitions of different fuel properties.
Step 3: Detailed Explanation:
Cloud point is the temperature at which wax crystals start forming.
Pour point is the lowest temperature at which fuel ceases to flow.
Flash point is the temperature at which fuel vapors ignite.
Aniline point is the temperature at which aniline and fuel are completely miscible.
Thus, the lowest temperature at which fuel ceases to flow is the pour point.
Step 4: Final Answer:
The lowest temperature at which fuel ceases to flow is the pour point.
Hence, the correct option is (B).
