Anonymous users2024-02-13The principle of floating eggs in salt water is that the density of salt water is higher than that of eggs, so the eggs will float.
The buoyancy is related to the volume of the object immersed in the liquid and the density of the liquid, the volume of the egg is fixed, then the density of the liquid will increase until the density of the liquid is higher than that of the egg. Not all brine can float eggs, and it is necessary to have a brine density greater than the density of the eggs.
Application of density.
1. Identify the materials that make up the object.
Density is one of the properties of matter, each substance has a certain density, and the density of different substances is generally different. Therefore, we can use density to identify substances. The method is to determine the density of the substance to be measured, and the measured density and density table.
By comparing the densities of various substances, it is possible to identify what substances are made of objects.
2. Calculate the composition of various substances contained in the object.
3. Calculate the mass of an object that is difficult to weigh or the volume of an object with a complex shape.

Anonymous users2024-02-12The principle of saltwater floating eggs is that because the density of the eggs is less than the density of the saltwater, the eggs will float on top of the saltwater. When water is added to the brine, the density of the brine decreases, and when the density of the brine is less than that of the egg, the egg sinks. In terms of the relationship between force and motion, when the egg is immersed in water, its buoyancy is less than the gravitational force, and the resultant force is downward, so the egg sinks.

5 answers2024-07-28Measuring principle: The float switch uses magnetic force to operate, and the inorganic mechanical connection is simple and reliable to operate. When the float switches the floating float of the measured medium, the float drives the main body to move, and the magnet at the other end of the float switches the magnet on the control lever at the same time. >>>More
15 answers2024-07-28。For a given object (i.e., the so-called egg), the greater the density of the medium (i.e., the density of water), the greater the buoyancy experienced. When the buoyancy is greater than the gravitational force on it, the egg begins to float, and when the egg is exposed to the water, the egg decreases in size and buoyancy until its buoyancy and gravity are back in balance, and the egg is still on the water.
