Material Properties Vocabulary W1-mt_MVovx37Xct-s1

  1. Transparent · Transparent glass gives a clear view. This does not mean that all light passes through.
  2. Conductor · Copper is an electrical conductor because current flows through it easily.
  3. False · Easy current flow describes a conductor. An electrical insulator resists current flow.
  4. Flexible · Easy bending without breaking shows flexibility. Springing back is a separate property.
  5. Opaque · Blocking visible light is the property called opaque.
  6. Soluble · Salt is soluble in water. The dissolved salt remains in the water.
  7. Electrical insulator and thermal insulator · Electrical insulation resists current flow. Thermal insulation slows heat transfer. The handle can still become hot.
  8. Transparent, rigid, insoluble, low density · Transparent gives a clear view, rigid resists bending, insoluble describes not dissolving in water, and low density means little mass for the volume.
