Answer to Question #305899 in General Chemistry for Mems

Question

Differentiate the types of moving particles (normal, slow and fast moving particles) when they approach each other before collision, during collision and after collision.

Answer 1

In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature .Heavier particles move more slowly than lighter ones at the same temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

In a solid, the particles pack together as tightly as possible. The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.
