Answer

Physical Properties and States of Matter

Physical Properties of Matter:

Physical properties are characteristics that can be observed or measured without changing the composition of a substance.
Examples of physical properties include color, density, melting point, boiling point, and conductivity.
These properties help identify and classify different types of matter.

States of Matter:

Matter exists in four main states: solid, liquid, gas, and plasma.
Solids have a definite shape and volume, with particles closely packed together in a fixed arrangement.
Liquids have a definite volume but take the shape of their container, with particles able to move past one another.
Gases have neither a definite shape nor volume, with particles moving freely and filling the entire space available.
Plasma is a fourth state of matter found at high temperatures, where particles are ionized and electrically conductive.
