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?

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.

Geothermic gradient is the rate of increasing temperature with respect to increasing the depth in the earths interior. away from tech tonic plates boundaries, it is about 25-40 c/km (72-87 degrees f/mi) of depth near the surface in most of the world.

This would be an open primary. a closed primary people can vote only prior to election day if the party if they are registered. independent voters can not participate. there is not a wide-open primary, but there is a semi-open primary.
