Understanding Matter and Its Properties
Matter is anything that has mass and takes up space (has volume). When studying matter, scientists look at two key aspects: its composition (what it's made of) and its properties (characteristics that describe it).
Properties of matter fall into two main categories. Physical properties describe matter without changing its chemical makeup - things like color, density, and melting point. Chemical properties describe how a substance reacts with other substances and potentially changes its composition.
Physical properties can be further divided into intensive properties (which don't depend on amount, like color or density) and extensive properties (which do depend on amount, like mass or volume). For example, a basketball's color remains orange regardless of its size (intensive), but its mass changes if you cut it in half (extensive).
Did you know? Every substance has a unique set of properties that acts like its "fingerprint," allowing scientists to identify unknown materials based on careful observation and testing.
