Answer 2

Answer:

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️

• Matter can be classified according to physical and chemical properties. Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition.
• A mixture is formed by combining two or more materials. A homogeneous mixture appears uniform, regardless of where you sample it. ... Examples of homogeneous mixtures include air, saline solution, most alloys, and bitumen. Examples of heterogeneous mixtures include sand, oil and water, and chicken noodle soup
• Examples of Physical Properties of Matter
• Commonly used examples include density, color, odor, hardness, and volume. Physical properties are further classified based on whether they are extensive or intensive. Extensive physical properties are those that are dependent on the amount of the substance present.
