Question

In a liquid, objects denser than the liquid tend to sink, while objects less dense

than the liquid tend to rise. How does this relate to the observed motions of the
liquid in the beaker?

Answer 1

Objects denser than a liquid tend to sink, while objects less dense than a liquid tend to rise in the liquid. This is because of the concept of buoyancy.

Step-by-step explanation:

In a liquid, objects denser than the liquid tend to sink, while objects less dense than the liquid tend to rise. This observation is related to the motion of the liquid in a beaker because of the concept of buoyancy which deals with the upward force exerted by a fluid on an object immersed in it. When an object is denser than the liquid, it displaces less liquid and experiences a downward force greater than the upward buoyant force, causing it to sink. Conversely, when an object is less dense than the liquid, it displaces more liquid and experiences an upward buoyant force greater than the downward force, causing it to rise.

Answer 2

If an object that is put in a fluid weighs more than the weight of the fluid it displaces, it will sink. Buoyancy is then, directly related to the weight, or density, of the fluid. A more dense, or heavier fluid will then have the ability to “float” heavier objects. true floating object must be wholly above the surface of the liquid. all objects that float must contain some trapped air and that is the only reason why they float. the amount of liquid on which the object floats matters somehow, i.e. an object will float higher in a larger volume or deeper liquid. The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in. If the density of an object in the fluid is greater than the density of the fluid, the object will sink. If the density is less than that of the fluid, the object will float upward due to the buoyancy from the fluid. Buoyant force is the product of displaced volume times density of the fluid times the acceleration due gravity. Hence increasing the density of fluid will increase the buoyant force.
