Ans 1 .a. There are no attractions between particles.
Kinetic molecular theory explains the property of gases assuming that the particles are perfectly elastic that is sphere, they are in continious random motion and there is no net attractive or repulsive forces in between them. The motion or the velocity of these particles depend upon the temperature of the system.
