What is boiency?

Answer 1

Boiency appears to be a misspelling or a typo, as it doesn't correspond to a recognized term in English. If you meant "buoyancy," it refers to the ability of an object to float in a fluid, determined by the object's density relative to the fluid's density. An object will float if it is less dense than the fluid, and it will sink if it is more dense. If you meant something else, please provide clarification!
