Reasoning: Matter is defined as anything that has mass and occupies space. All physical substances around us, whether solid, liquid, or gas, are forms of matter.

Reasoning: Matter exists in three main states: solid, liquid, and gas. Therefore, all the given options are correct states of matter.

Reasoning: Macroscopic properties are those that can be observed directly without any instrument, meaning they are visible to the naked eye, such as color, shape, and size.

Reasoning: Matter is characterized by both physical properties (like color, density, state) and chemical properties (like reactivity, flammability). Both types together fully describe a substance.

Reasoning: A compound is formed when two or more different elements chemically combine in a fixed ratio, such as water (H2O) formed from hydrogen and oxygen.
