unsaturated fats
Any sort of vegetable oil is usually liquid at room temperature.

True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
Trans fats made from plant sources of fat. Plant fats tend to comprise mostly of unsaturated fatty acids which is why oils are not solid. They are chemically altered to have more hydrogen which results in them being more solid like animal fats such as butter which are higher in saturated fatty acids. Chemically trans fats are unsaturated fats but structurally they are like saturated fats.
Animal fats tend to go rancid with time. Vegetable oils will too eventually, but have a longer shelf life.
Soaps made from vegetable oils tend to be milder and less harsh on the skin compared to soaps made from animal fats. They also often have better lathering properties and are more environmentally-friendly due to being derived from renewable plant sources.
Fats crystallize when they are frozen. Oils tend crystallize or freeze at temperatures below room temperature (72°C). Fats tend to be frozen at room temperature. Fats can crystallize with different crystal structure. The crystal structure affects the stability and quality of the fat.
Unsaturated fats, such as oils, are typically liquid at room temperature due to their structure with double bonds that prevent tight packing of molecules. In contrast, saturated fats, which have no double bonds, are usually solid at room temperature.
Oils typically have higher iodine numbers than fats. Iodine number is a measure of the degree of unsaturation in fats and oils, with higher numbers indicating more double bonds and thus greater unsaturation. Oils, which are liquid at room temperature, tend to have more unsaturated fatty acids compared to fats, which are solid at room temperature.
Fatty acids are hydrophobic molecules and are insoluble in water. However, they can be incorporated into larger structures like triglycerides or phospholipids that can be both water-soluble and insoluble. Oils, which are liquid fats, tend to contain a higher proportion of unsaturated fatty acids, making them more fluid at room temperature compared to solid fats.
Hydrogenation adds hydrogen atoms to the double bonds in unsaturated fats which converts them to semisoild material, which is similar to that of saturated fats (they tend to be solid since their formation is generally stronger than that of unsaturated) The similarities; (semi)solid form. For example; margarine.
