Final answer:
Hard waxes are typically used for hair removal, are solid at room temperature, and are insoluble in water. They are pliable upon melting and serve a variety of industrial and natural functions. Unlike an incorrect statement provided, they do not melt at particularly low temperatures and are not water-soluble.
Step-by-step explanation:
The correct statements that describe hard waxes include that they are typically used for hair removal and are solid at room temperature. Contrary to an incorrect option, hard waxes are not water-soluble; in fact, waxes are insoluble in water due to their nonpolar hydrocarbon chains. Additionally, waxes have low melting points relative to other substances but are not necessarily classified as melting at a low temperature. Another characteristic of waxes is their pliability after melting, but this does not mean they are soft and pliable at room temperature like the incorrect option might suggest.
Natural waxes, such as beeswax and lanolin, serve various functions including providing a waterproof and pliable coating to the leaves of plants and the skin, hair or feathers of animals. Synthetic waxes are used for many applications, ranging from lubrication to waterproofing and as a component in various polishes.
While hard waxes and saturated fats share the property of being solid at room temperature and having single bonds in their carbon chains, they significantly differ in that waxes do not dissolve in water easily.
