Arrange these less-flammable liquids in order of highest to lowest fire point: Silicone, FR-3, Bio-temp, R-temp, Beta, Mineral.

The fire point of a liquid is a crucial factor in assessing its flammability and safety in various applications. In considering the arrangement from highest to lowest fire point, knowing the specific characteristics of the listed liquids helps determine their order.

Silicone typically has a high fire point due to its chemical structure, which is stable and resistant to combustion. Following silicone, FR-3 is recognized for its high fire point as it is an ester that is designed to be less flammable compared to many mineral oils, making it safe for various applications. Next in line, Bio-temp scores well in fire point, as it is formulated for better performance in high-temperature environments.

R-temp generally has a lower fire point compared to these synthetic and bio-based oil alternatives, which are engineered to resist ignition more effectively. Beta and Mineral oils are often lower on the list due to their compositional differences and lower thermal stability, resulting in a reduced fire point compared to the above products.

Thus, the order of fire points from highest to lowest accurately reflects the specific characteristics of each substance in that context.
