Fats turn into an "oil" when they melt.
Oils are fats which are liquid at room temperature, waxes are fats which are solid at room temperature. Both waxes and oils can be emulsified. Chemicaly waxes and oils consist of hydrocarbons or esters of fatty acids, they are insoluble in water but soluble in nonpolar organic solvents. The difference in class is based on melting point and larger molecules tend to melt at higer temperatures and are more likely to be waxes, however side chains can lower melting points and hydrogen bonding can raise them. In summary the classification into oil or wax is due to the size of the hydrocarbon and its complexity.

glycerin is the by-product
Lipids are fats such as waxes, hormones, and oils.
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 are technically unsaturated fats. In cis-fats (healthy) hydrogens are on the same side at the double bond. This gives the molecule a deformed shape that does not pack well. This has an effect of lowering the melting point. In trans-fat the hydrogens are on opposite sides of the double bond. This is more stable and allows tighter packing. Thus trans-fats have higher melting points.H RC::CR HTransR RC::CH HCis
Higher in saturated fatty acids
because they have different melting/ boiling points.
Both are medium to long chain fatty acids. Fats whether from animal or plant origins are more saturated than oils, resulting in a higher melting point. Animal fats and oils usually contain some cholesterol, vegetable fats and oils never contain any cholesterol.Fatty acids are hydrocarbon chain molecules with a carboxylic acid group replacing the hydrogen atom at one end of the molecule.
Lipids.
Vegetable fats and oils are lipid materials derived from plants. Physically, oils are liquid at room temperature, and fats are solid. Chemically, both fats and oils are composed of triglycerides, as contrasted with waxes which lack glycerin in their structure. Although many different parts of plants may yield oil,[1] in commercial practice, oil is extracted primarily from seeds.The melting temperature distinction between oils and fats is imprecise, since definitions of room temperature vary, and typically natural oils have a melting range instead of a single melting point since natural oils are not chemically homogenous. Although thought of as esters of glycerin and a varying blend of fatty acids, fats and oils also typically contain free fatty acids, mono- and di- glycerides, and unsaponifiable lipids.Vegetable fats and oils may or may not be edible. Examples of inedible vegetable fats and oils include processed linseed oil, tung oil, and castor oil used in lubricants, paints, cosmetics, pharmaceuticals, and other industrial purposes.

The healthiest oils are oils that have polyunsaturated and monounsaturated fats. The healthiest oils are oils packed with saturated fats.
Lipids are commonly called fats and oils.
