    The given has to be named as a pure substances and mixture along with phases. Concept Introduction: If a kind of matter cannot be separated into other kinds of matter by any physical process is known as substance. A mixture that has physically distinguishable parts of each having different properties is known as Heterogeneous mixture.   To a non-chemist, a pure substance is anything composed of a single type of material. In other words, it is free of contaminants. So, in addition to elements, compounds, and alloys, a pure substance might include honey, even though it consists of many different types of molecules.
