Taking cooking oil as an example, 10 liters of oil is equal to 18.6 pounds. According to the physical formula: quality = density multiplied by volume, the density of cooking oil is 0.93kg / L, 10 * 0.93 = 9.3kg, converted into pounds is 18.6 pounds.
The density of each oil is not the same, can be converted according to the density formula, the density of fats and oils between 0.91g/ml-0.93g/ml. Kerosene 0.8g/cm^3, vegetable oil 0.9g/cm^3, gasoline 0.71g/cm^3, the density of diesel is 0.84g/cm^3. gasoline has a density of 0.70g/cm^3, and soy sauce has a density of 1.15g/cm^3.
Expanded information: In general, no matter what the substance is, and no matter what state it is in, with the change of temperature and pressure, the volume or density will also change accordingly. The equation relating the three physical quantities temperature T, pressure F and density ρ (or volume) is called the equation of state. The volume of a gas varies significantly with the pressure to which it is subjected and the temperature at which it is exposed. For an ideal gas. The density of a solid or liquid substance changes only very slightly as the temperature and pressure change. For example, near 0°C, the temperature coefficients (the rate of change in the volume of an object when the temperature rises by 1°C) of various metals are mostly around 10-9. Pressure in deep water and underwater explosion when the pressure can reach several hundred atmospheres, or even higher (1 atm = 101325 Pa), this time the density must be considered with the change in pressure.
