MATTER

MATTER. PHYSICAL PROPERTIES. SOLID. Has a fixed shape & volume. Particles are tightly compact. Each particle has its fixed place. Particles can vibrate but cannot move freely. Cannot be compressed. Lowest energy state of matter. LIQUID. Fixed volume Changeable shape.

  1. MATTER PHYSICAL PROPERTIES

  2. SOLID • Has a fixed shape & volume. • Particles are tightly compact. • Each particle has its fixed place. • Particles can vibrate but cannot move freely. • Cannot be compressed. • Lowest energy state of matter.

  3. LIQUID • Fixed volume • Changeable shape. • Take the shape of the container. • Particles are compact enough to keep the volume but free enough to change the shape. • Like solids, liquids can not be compressed. • Moderate energy state of matter.

  4. GAS • No definite shape & Volume. • Particles can easily spread out or move closely together. • Take the shape of the container. • Can be compressed. • Example: in a bicycle tire. • High energy state of matter.

  5. Changes of States in Matter

  6. What Causes State Changes?

  7. Physical properties of matter Density: • The amount of matter in a given volume. • Density = mass/volume • Is unique for every substance. • Does not depend or vary with the size of the sample. • Is always constant.

  8. Physical properties of matter Melting point: • Is the temperature at which a substance changes its state from solid to liquid. • Is unique for every substance. • Is not affected by the size of the sample.

  9. Physical properties of matter Texture: • How a substance feels or looks. • Also, the size, shape, & pattern of a rock’s grain • Sand paper is rough. • Glass is smooth.

  10. Physical properties of matter Conductivity: • Ability of a substance to allow heat and electricity to flow through it. • Metals like iron & copper are good conductors and rubber is not.

  11. Physical properties of matter Luster: • The way a substance reflects light. • Dull, earthy, metallic, greasy, pearly, glassy, & silky are words used to describe the luster of substances.

  12. Physical properties of matter Malleability: • Ability of a substance to be hammered/ pounded into sheets. • Most metals like silver, lead, and copper, are highly malleable.

  13. Physical properties of matter Hardness: • Ability of a substance to resist scratching or get scratched easily. • Is measured on the Mohs Hardness Scale. • Talc is the softest and diamond is the hardest substance 0n the Mohs hardness scale.

  14. Physical properties of matter Ductility: • Ability of a substance to be drawn into wires. • Metals like aluminum & copper can be easily drawn into wires & are used in electrical cords.

  15. STREAK • Color of a mineral in it powdered form. • Can be obtained by rubbing the mineral across a streak plate-- a piece of unglazed porcelain tile. • Example: hematite always gives a reddish brown streak no matter what type of luster it displays.
