The density of water is: 1.0×10 cubed. Oil is: 0.71×10 cubed.

Water is usually a colorless, odorless liquid.

Boiling point: 99.975℃ (when the air pressure is one standard atmospheric pressure, it is 101.325kPa).

Freezing point: 0℃

Triple point: 0.01℃

Temperature at maximum relative density: 3.982℃

Specific heat capacity: 4.186 kJ/(kg·℃) 0.1MPa 15℃ Latent heat of evaporation: 2257.2kJ/(kg) 0.1MPa 100℃

Oil is a general term for hydrophobic substances that are liquid at room temperature and consists of one or more It is composed of liquid hydrocarbons (a large part of silicone oil is composed of silicone compounds). The difference from hydrocarbons such as alcohols, ketones and ethers is that the components of the oil are not polarized. The difference from fat is that the molecular lengths of the compounds that make up oil and the connections between molecules are smaller.

Extended information:

Chemically, bio-oils are glycerin. The difference between them and fats is that their melting points are lower than fats.

Many vegetable oils are used for food (such as vegetable oil, sunflower oil, olive oil, etc.). Relatively few animal oils are used as edible oils (such as cod liver oil), and the distinction between animal oils and fats is not very clear. In addition, animal oil is also used in industry to make lubricants, soaps, etc.

When the water temperature drops to 0℃, the water freezes into ice. When the water freezes, almost all the molecules associate together to form a huge associated molecule. The arrangement of water molecules in the ice is that each oxygen The atoms have four hydrogen atoms and two adjacent hydrogen bonds. This arrangement results in an open structure. There are large gaps in the ice structure, so the density of ice is inversely smaller than that of water at the same temperature.
