  1. Solids, Liquids, and Gases States of Matter

  2. States of Matter • All matter takes up space and has mass • There are 4 states of matter • Example: Water • The state of matter depends on temperature.

  3. Solids • Crystalline solids • Particles are arranged in repeating geometric patterns called crystals. • Noncrystalline solids • No crystals • “amorphous solids” • Thick liquids • Ie: glass, plastics, wax • Every solid has a definite shape and a definite volume.

  4. Liquids • A liquid flows and takes the shape of its container. • Liquids can’t normally be squeezed to a smaller volume. • Example: Ice cream

  5. Gases • “springy” • Expand or contract to fill the space available to them. • Can be squeezed into smaller space. • Particles are free to move in all directions until they have spread evenly throughout their container.

  6. Plasma • The most common state of matter in the universe. • Found in stars (the sun) and nebula. (p. 218) • A gaslike mixture of positively and negatively charge particles. • Thermal Expansion • As a solid is heated, particles move faster • vibrate against each other • particles spread apart in all directions • Solid expands

  7. The Kinetic Theory of MatterTiny particles in constant motion make up all matter.
