Oil does mix with other substances for instance if you had some pure ethanol, oil would dissolve in it.
Different types of powder
'Solubility' . NB Different substances have different solubilities. NNB All Group 1 metals are soluble. All nitrates are soluble Most chlorides are soluble or partially soluble Sulphates are insoluble. NNNB There is a table of solubilities for different substances in Wikipedia.
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
Many different substances dissolve easily in water, but there are some which don't, particularly oily substances. Soap makes these substances dissolve in water.
Oil and sand are two substances that will not dissolve in water.
No. Some substances dissolve perfectly and are called homogeneous. Others do not and are called Heterogeneous.
Oil does mix with other substances for instance if you had some pure ethanol, oil would dissolve in it.
Substances that do not dissolve are insolubles, because they are not soluble they do not dissolve.

Water is a polar substance, which means that any other polar substances will dissolve in it. The opposite is mineral turpentine which is non-polar so all non-polar substances dissolve in it.
The chemistry principal of "like dissolves like," explains that polar substances will dissolve in each other. Similarly, a covalent will dissolve another covalent.
None of these are pure substances. All are mixtures.
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
all i know is that solutes lower its freezing point but i kinda think they dissolve into a liquid.
All substances are dissolved faster at high temperature.
No, not at all. In fact most solids are INsoluble. Some solids (such as metals, stones, wood) don't dissolve while other solids like sugar or salt do dissolve. Water is a polar molecule, therefore it can dissolve only polar substances and many ionic compounds. However, it cannot dissolve non-polar substances.
