Regents Chemistry Exam August 2024 Question 19
19 According to the kinetic molecular theory, the particles of an ideal gas
(1) constantly move in circular paths
(2) have no attractive forces between them
(3) do not transfer energy when the particles collide
(4) are separated by small distances relative to their sizes
Solution:
According to the kinetic molecular theory
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.
Choice 2 is the correct answer
