Questions and Answers

What is the main idea of the text?

  • Liquids with stronger IMFA have lower surface tension.
  • Substances with weaker IMFA have higher boiling points.
  • Polar molecules and nonpolar molecules mix together.
  • The stronger the IMFA between solute and solvent molecules, the greater the solubility. (correct)

    • What is the definition of solubility?

  • The ability of two liquids to dissolve together.
  • The tendency of a fluid to acquire the least possible surface area.
  • The temperature at which a substance changes from solid to liquid.
  • The ability of a solute to dissolve in a given solvent. (correct)

    • What is the effect of stronger IMFAs on melting points?

  • Substances with weaker IMFAs have higher melting points.
  • Substances with stronger IMFAs have higher melting points. (correct)
  • Substances with stronger IMFAs have lower melting points.
  • IMFAs have no effect on melting points.
