Concept:In the kinetic molecular model, gas particles are in constant, rapid, random motion and are widely separated.
Explanation:The kinetic molecular theory describes an ideal gas as a collection of tiny particles in continuous straight-line motion.
These particles are very far apart compared to their own size.
Because the particles move freely and rapidly, they spread out to fill the entire container available to them.
The large spaces between particles and their high kinetic energy overcome any weak intermolecular forces.
Thus, gases do not have a fixed shape or volume; they occupy all the space made available.
Option A describes a solid, where particles are closely packed in a regular pattern.
Option D describes a solid, where particles vibrate about fixed positions with strong bonds.
Option B is not an accurate description of a gas.
Answer:The correct option is C: The molecules are very far apart and occupy all the space made available.
