The density of eggs is less than that of salt water, so eggs will float on the salt water. According to physical knowledge, F float = ρ gV discharges liquid, ρ is the density of liquid, and v is the volume of discharged liquid. Equal to the volume of the object immersed in the liquid (suspension, precipitation: the whole object is in the liquid, and line V is equal to the volume of the object; Floating: a part of the object is in the liquid, and the V line is equal to the volume of the submerged part).

When the egg volume is constant and the liquid density increases, the buoyancy increases accordingly. Adding salt to water will increase the density of liquid, so eggs will float in salt water.

1. If the density of salt water is greater than that of eggs, will eggs float?

2. If the density of salt water = the density of eggs, the eggs are suspended in the liquid?

If the density of salt water is less than that of eggs, the eggs will sink.

buoyancy

1. Buoyancy: An object submerged in a liquid (or gas) is pushed upward by the liquid (or gas).

2. Buoyancy direction: opposite to gravity direction, vertical upward.

3. Causes of buoyancy: An object immersed in liquid or gas is subjected to the upward and downward pressure difference of the liquid or gas on the object.

4. When the top interface of the floating body can't touch the liquid, only the upward pressure acting on the bottom interface will produce buoyancy. As for the object at the bottom of the container, this phenomenon is relatively rare, because as long as there is a thin liquid film between the two, the pressure can be transmitted, there is upward pressure at the bottom, and there is a pressure difference between the upper and lower surfaces of the object, and the object will be floated.
