Explanation:

The text provided is a part of a study material on the "Classification of Matter" and "Composition of Matter" but does not contain a specific question. If you want to know about the classification of matter (e.g., elements, compounds, mixtures; or solids, liquids, gases), or about the composition of matter (like atoms, molecules, etc.), please clarify your question. For example, if you want to know how matter is classified based on composition, here is a brief explanation:

Matter can be classified based on composition into pure substances (elements and compounds) and mixtures (homogeneous and heterogeneous). Elements are made of only one type of atom, compounds are made of two or more different atoms chemically bonded. Mixtures have two or more substances physically combined. Based on state, matter is solid (definite shape and volume), liquid (definite volume, indefinite shape), gas (indefinite shape and volume).

Answer:

Matter is classified by composition (pure substances: elements, compounds; mixtures: homogeneous, heterogeneous) and state (solid, liquid, gas). (If you had a specific question like "What are the types of matter based on composition?", this would be the answer. Please provide a more specific question for a more targeted response.)
