Does the density of gasoline increase or decrease with the increase of temperature?

Get smaller.

The analysis process is as follows:

Like most substances, gasoline has the characteristics of expanding when heated and contracting when cooled. In summer, with the increase of temperature, the density of gasoline will become smaller.

When the temperature rises, the volume of gasoline increases. According to ρ=m/v, m remains unchanged, v increases and ρ decreases.

When the temperature decreases, the volume of gasoline decreases. According to ρ=m/v, m remains unchanged, v decreases and ρ increases.

Extended data:

Gasoline is one of the most commonly used light petroleum products and an important fuel for engines. According to the manufacturing process, gasoline components can be divided into straight-run gasoline, thermal cracking gasoline (coking gasoline), catalytic cracking gasoline, catalytic reforming gasoline, superimposed gasoline, hydrocracking gasoline, alkylated gasoline and synthetic gasoline.

Gasoline products can be divided into aviation gasoline, automobile gasoline and solvent gasoline according to their uses. The first two kinds are mainly used as fuels for gasoline engines, which are widely used in automobiles, motorcycles, speedboats, helicopters, agricultural and forestry planes and so on.

Solvent gasoline is used to produce synthetic rubber, paint, grease and perfume. Gasoline components can also dissolve oil stains and other water-insoluble substances, and play a role in cleaning oil stains; As an organic solution, the gasoline component can also be used as an extractant.
