In the saltwater of the eggs why the pointed head down

During the incubation process of eggs, the embryo needs oxygen, but the outside is the eggshell, and the air chamber can provide a certain amount of oxygen to meet the amount of oxygen required by the embryo during development! Depending on the cell developmental structure, the air chamber is generally located at the blunt head of the egg. Because the specific gravity of the egg is greater than that of fresh water, the egg will sink when placed in the water, and although the air chamber end produces buoyancy, the upward buoyancy cannot drive the egg body vertically upward.

The specific gravity of saltwater is similar to that of an egg, and the buoyancy of the egg body rises (canceling out part of the gravity), and the buoyancy of the air chamber also increases, so that the egg is pointed down and blunt head up in saltwater.

According to the cell structure of the egg, in addition to providing certain nutrients before the egg hatches out of the chick, there must also be gas for the little life to breathe, so the blunt end of the egg is the place where the gas is stored. That is, the air chamber mentioned in the textbook, the density of salt water is relatively large, when there is an egg containing an air chamber put inside, the tip of the denser is downward, and the blunt head containing the air chamber is naturally upward.

The tip is empty, the center of gravity is higher with the tip up than the point down, the lower the center of gravity, the more stable, even if you make the tip up, it will be the other way around.

Because the pointed end is solid, it is heavier.

Because there is a cavity at the blunt end, and the pointed end is solid.

The pointed end is solid, and there are gaps and air buoyancy at the round head, so the round head is facing up.

The non-pointed end is the air chamber of the egg, which is less dense.

Answer: The round head side should "breathe"! (There is air).

Because the density of the brine is not less than the density of the eggs.

When the density of the liquid is greater than the density of the egg, it will float, if the density is equal to the egg, it will be suspended in the liquid, if it is less than the density of the egg, it will still be calm.

Reason: f (buoyancy) = p (density of liquid) * newton kg * v (volume of liquid dispelled by the object, i.e. volume of the object).

Since only the density will change, and the density = mass volume, as long as enough salt is added to increase the mass of the liquid, the density will increase.

Because of the high density of saltwater, the buoyancy experienced by the egg in it is equal to its own gravity, so the egg will float on the surface of the saltwater water. Junior high school physics should have been learned.

Salt water is denser than water, and of course floats.

Because the salty water is salty to a certain extent, the density will be greater than the average density of the egg, so the buoyancy received by the egg in the water is greater than the gravitational force it receives, and the combined force of these two forces is upward, so the egg will float in the salty water.

When it comes to physical knowledge, the density of saltwater is relatively large, and the density inside the egg is smaller, and the pressure in the water is greater when the water is heated, so it is ......

The salt water is dense and buoyant is greater than the gravity of the egg, so it floats.

The density of salt water is high, which can be explained in physics, I have been away from school for a long time, and you should go to learn junior 3 physics.

Because the density of eggs is less than the density of brine.

Because the density of brine is not less than that of eggs.

When the density of the liquid is greater than the density of the egg, it will float, if the density is equal to the egg, then the suspension is in the liquid, if it is less than the density of the egg, it is still calm.

Reason: f (buoyancy) = p (density of liquid) * newton kg * v (volume of liquid that the object is discarded, i.e. the volume of the object).

Since only the density will change, and the density = mass volume, as long as enough salt is added to increase the mass of the liquid, the density will increase.

Because the density of salt water is greater than that of ordinary water, and then its density is greater than that of the egg, so the egg floats.
