NY Regents Chemistry Exam August 2023 Question 17
17. According to the kinetic molecular theory, ideal gas particles
(1) are separated by small distances relative to their size
(2) do not transfer energy when they collide with each other
(3) have attractive forces between them
(4) move in random, constant, straight-line motion
Solution: We need to memorize that according to the Kinetic Molecular Theory of Ideal Gases
Gas particles have negligible volume.
The gas particles are in continuous random motion and move in straight lines.
No forces of attraction or repulsion are considered to exist between the particles.
Collisions of gas particles may transfer energy from one particle to another, but the total kinetic energy remains the same. Out of the answer choices given, choice 4 is the correct answer.
