1. Which of the following correctly defines the principles of kinetic molecular theory? a. There are no attractions between particles. b. The space between the particles is the same as the size of the particles. c. Particles move slower when temperature increases. d. When particles collide, they become motionless.

Answer;

A. There are no attractions between particles

Explanation; The kinetic molecular theory is based on the principle that there is no forces of attraction between gas particles or between the particles and the walls of the container. Other principles includes; the average kinetic energy of gas particles depends on the temperature of the gas alone, Collisions between gas particles and the walls of the container are perfectly elastic and also the particles are in a constant random motion
