Regents Chemistry Exam June 2025 Question 14

14 According to the kinetic molecular theory, which statement describes the particles of an ideal gas?

(1)  The force of attraction between the particles is strong.

(2)  The particles are arranged in a regular, geometric pattern.

(3)  The particles move in random, constant, straight-line motion.

(4)  The collisions between particles result in a net loss of energy.

Solution:

Kinetic Molecular Theory of Ideal Gases States That

1. Gas particles have negligible volume.

2.  The gas particles are in continuous random motion and move in straight lines.

3. No forces of attraction or repulsion are considered to exist between the particles.

4. Collisions of gas particles may transfer energy from one particle to another, but the total kinetic energy remains the same.

   
   

   Choice 3 is the correct answer.
