Which liquid has the highest ignition temperature?

Acetone has the highest ignition temperature among the liquids listed. The ignition temperature refers to the minimum temperature at which a substance will ignite and sustain combustion. Acetone, a highly volatile organic solvent, has a higher ignition temperature compared to the other options, which means it requires more heat to ignite.

Gasoline is known for its low ignition temperature, making it highly flammable. Kerosene, although also flammable, has a lower ignition temperature than acetone, making it easier to ignite. Ethanol, while it burns readily, has a lower ignition temperature than acetone as well.

Understanding ignition temperatures is crucial, especially in firefighting and hazardous materials handling, as it helps responders assess the risks associated with different substances and manage those risks effectively.
