We will explore how these molecules are getting through the basketball. Effusion is when small gaseous particles have high kinetic energy that allows them to move through small holes. However, the mean free path must be larger the hole itself. The mean free path is the average distance traveled by a particle between collisions with other particles (¨Boundless¨ 10/13/16). If it does not meet these requirements, then the gas molecules will just keep moving back and forth through the opening. Effusion tells how gas molecules move through the small opening of the basketball, leading to an increase in its air pressure; this similar to the Kinetic Molecular …show more content…
For example, on the men’s professional level, or the NBA, the basketball has a circumference varying between 75-76 cm. Whereas for the women’s, the basketball’s circumference is between 72-74 cm. However, the exterior and interior of a basketball is the same regardless of what level it is played on, or what of type brand name the ball is. The exterior of a basketball is made of synthetic rubber, rubber, composition, or leather (“How products are made” 10/11/16). Every basketball is made out of one of these 4 coverings. The interior also contains something that every basketballs needs, a bladder, and carcass. The bladder is made of butyl rubber, and the carcass consists of threads of nylon or polyester (“How products are made” 10/11/16). When the distributors are finished making the basketball as whole, they test, inspect, and put them in packages . Overall, these two qualities are in every single basketball that are
