Yes, buoyancy is different in different liquids.
Buoyancy, the upward force exerted by a fluid that opposes the weight of an immersed object, depends on the density of the fluid. The buoyant force (FB) can be calculated using the formula:
FB = V ρ g
Where:
- V is the volume of the object immersed in the fluid.
- ρ (rho) is the density of the fluid.
- g is the acceleration due to gravity.
Since different liquids have different densities (ρ), the buoyant force (FB) acting on the same object immersed in those different liquids will be different, assuming the object is fully or partially submerged in each liquid.
Example:
Imagine the same block of wood submerged in water and then in oil. Water has a density of approximately 1000 kg/m³, while a typical oil might have a density of around 900 kg/m³. Because water is denser, the buoyant force acting on the wood in water will be greater than the buoyant force acting on the wood in oil. This difference in buoyant force would result in the wood floating higher in water than in oil.
In Summary:
The buoyant force experienced by an object immersed in a liquid directly correlates with the liquid's density. A denser liquid will exert a greater buoyant force than a less dense liquid on the same object.
