kerosene

This substance is characterized by its high volatility and energy density, making it the standard choice for aviation turbine engines. It is often perceived as a cleaner-burning alternative to crude oil but carries a strong, distinct chemical odor associated with industrial heating and lighting. As a mass noun, kerosene is uncountable. It refers to the substance in general and cannot be pluralized to describe multiple units of the liquid; instead, partitive constructions such as "a gallon of kerosene" or "a liter of kerosene" must be used to specify quantity.
