If Kofi and Aya are both wearing inflatable arm bands to help them float in a pool, and Kofi's arm bands are inflated to a higher pressure than Aya's, what can be observed about the snugness of the bands around their arms and their buoyancy in the water? Respond very briefly.
Kofi's arm bands, being inflated to a higher pressure, will exert a greater force on his arms, making them fit more snugly compared to Aya's less inflated arm bands. As for buoyancy, assuming both arm bands are designed the same way and have the same volume when fully inflated, both Kofi and Aya will have similar buoyancy in the water because buoyancy is determined by the volume of water displaced by the arm bands, not by the pressure of the air inside them. However, if the greater pressure in Kofi's arm bands means they have less chance of compressing under water, they might maintain their shape and volume better, offering potentially more consistent buoyancy.
