Kinetic particle model of matter — practice question

Which row compares how far apart the molecules are and how they move in a hot gas versus a cool liquid? (The gas and the liquid are both at the same pressure.)

  • Aseparation: greater for a gas; motion: faster for a gas
  • Bseparation: greater for a gas; motion: slower for a gas
  • Cseparation: smaller for a gas; motion: faster for a gas
  • Dseparation: smaller for a gas; motion: slower for a gas
