What is the cause of Brownian motion?
Molecules in a gas move constantly, freely, randomly, in all directions and at high speeds. They are able to do so because the intermolecular force of attraction among the molecules is negligible when in a gaseous state. This constant motion of the molecules causes them to collide with anything in their path. For instance, dust particles will be bombarded by the molecules moving at high speeds, causing them to have a zigzag motion.
Define Poisson Distribution in Ideal Gas? Consider a monatomic ideal gas of total Ñ molecules in a volume V ˜ Show that the probability, P N for the number N of mole

What is the difference between diffraction and interference? Diffraction is the bending of waves around an obstacle, whereas interference is the meeting of two waves. For exam
