1. Use the pump to put one pump of gas into the box.
a. What happens to the clump of particles? ___The clump of particles disperses as they move in zigzag motion
after collision with other particles and walls of the container. ___
(To answer the following questions, keep your eye on one particle and notice how it moves.)
b. How do the particles move? (straight line, circular, random, etc.) ____Random_______
c. Do the particles stay at a constant speed? ______No________
d. If not, what causes the speed to change? _Loss of kinetic energy due to heating and maybe sound during
collision._
f. Do they always move in the same direction? ________No_________
g. If not, what causes their direction to change? ________Collision with other particles and the walls.__________
