The model of ideal gases shown above is useful because it ? predicts the behavior of other phases of matter. ? accurately approximates the properties of most gas molecules. ? shows a linear relation between gas pressure and volume. ? gives precise explanations for nonideal gas behavior.
The model of ideal gases shown above is useful because it
  1. ? predicts the behavior of other phases of matter.
  2. ? accurately approximates the properties of most gas molecules.
  3. ? shows a linear relation between gas pressure and volume.
  4. ? gives precise explanations for nonideal gas behavior.
Accurately approximates the properties of most gas molecules.
When a metal is heated in a flame, the flame has a distinctive color. This information was eventually extended to the study of stars because
  1. ? a red shift in star color indicates stars are moving away.
  2. ? star color indicates absolute distance.
  3. ? it allows the observer to determine the size of stars.
  4. ? the color spectra of stars indicate which elements are prese
