Study Notes

Properties of Matter

Liquids have particles that are loosely packed, allowing them to take the shape of their container.
Matter is any substance that occupies space and has mass.
Gas particles are widely spaced, move fast, and are randomly organized, resulting in no definite shape or volume; they have high kinetic energy.

Structure of Matter

Atoms and molecules are the fundamental building blocks of all matter.
Space is a boundless three-dimensional expanse where objects exist and events occur, defined by positions and directions.

Fundamental Quantities of Matter

Mass is a critical property measured in kilograms (Kg) and quantifies the amount of matter in an object.
The seven fundamental quantities of matter are: length, mass, time, electric current, temperature, amount of substance, and luminous intensity.

Physical Properties of Matter

Key physical properties include shape, size, color, and temperature, which describe the characteristics of matter without changing its identity.

Chemical Properties of Matter

Chemical properties involve how substances react and change, including reactivity, flammability, and the ability to rust.
A chemical change alters the composition of a substance, producing new forms of matter with different physical properties.

Law of Conservation of Matter

Matter can change in size, shape, and form, but the total mass remains constant before and after any transformation.
The quantity of matter is conserved; it is neither created nor destroyed in a chemical reaction or physical change.

States of Matter

There are three primary states: solid, liquid, and gas, with additional states including plasma, Bose-Einstein condensate, quark-gluon plasma, and degenerate matter.
