d=m/v. • Density of a substance is affected by temperature and pressure. These vary according to the physical properties of the substance. The effect of temperature on the density of solids and gases varies widely. Gases are most affected; solids are least and liquids ranging generally in between.
Buoyant force is the upward force exerted by a fluid on an object immersed in it. It is equal to the weight of the fluid that the object displaces.
To calculate buoyant force, use the formula Fb = ρVg, where Fb is the buoyant force, ρ is the density of the fluid, V is the volume of the fluid displaced, and g is the acceleration due to gravity.
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid it displaces. This principle helps explain why objects float or sink in fluids.
The shape of an object does not affect the buoyant force, as long as the object displaces the same volume of fluid. However, the shape can affect the weight of the object and therefore its ability to float or sink.
The depth at which an object is submerged does not affect the buoyant force, as long as the object remains fully immersed. However, the pressure and density of the fluid may change with depth, which can affect the weight of the object and therefore its buoyancy.
