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.
