What are some ways to make an egg float on water?

The principle of heating is that water molecules move rapidly when heated, causing the buoyancy of water to increase.

Yes, if you leave the boiled egg for a long time, it will float up.

Because egg whites are inherently liquid and dense close to water, coupled with the chamber on top of the egg, the overall density of the egg is less than that of water. That's why eggs float on the surface of the water.

There are numerous small holes in the shell of the egg that allow the egg to breathe. The surface of the egg shell also has a layer of water-soluble gelatinous substance, which is the same layer of gelatinous substance that prevents bacteria and water from entering, and the egg can only remain fresh for a period of time after it is laid.

When the egg is boiled, the yolk and egg white inside the egg are heated and expanded, and the gas inside the egg is expelled from the small holes on the surface of the egg. Because the gelatinous substance on the surface of the egg shell dissolves in the water when the egg is boiled, the small holes on the surface of the egg shell become larger, and the water can enter and exit freely. When the egg is cooled in cold water, the yolk and egg white cool and shrink, and the water will enter the egg, so that there is a lot of water in the egg shell, which increases the density of the egg and makes the egg sink to the bottom of the water.

Even if you take the hard-boiled egg out of the hot water immediately and put it back in the water after cooling, the egg will still float on the water at first, but you can see a lot of bubbles on the surface of the egg, and it will sink to the bottom after a while.

That's why eggs sink to the bottom of the water when they're cooked.

Liquid buoyancy》The gravity of an egg.

I don't know what to ask.

1. Put salt: Since the density of the egg is less than the density of the brine, the egg will float on top of the brine. 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, and the egg is immersed in salt water, the buoyancy is greater than the gravitational force, and the resultant force is upward, the egg floats, and the buoyancy decreases to equal to gravity, and the egg will float on it.

2. Sugar: Sugaring can also change the density of the water and make the eggs float to the surface.

3. Drip wax: increase the drainage volume of the egg, drip wax on the egg, the density of the wax is less than the density of water, if the wax is dripped on the egg, the gravity increase is not as fast as the buoyancy increases, so the egg can float.

Physical knowledge of objects floating on water with eggs:

The rise and fall in a liquid depends on the comparison of the buoyancy experienced by the object and the magnitude of gravity. Not the magnitude of buoyancy, nor the magnitude of gravity.

By changing the magnitude of gravity or buoyancy, the state of the object can be changed.

When f floats g, the object floats up, and the result of the float is floating.

When f floats g, the object sinks, and the result of sinking is sinking to the bottom.

When f floats g, the object is in a suspended or floating state (i.e., it remains in its original state) Note: The concepts of floating, floating, levitating, sinking, and sinking should be distinguished.

This one is a mistake, and it doesn't boil at all.

Pour the water into a glass approximately.

Five, six points full.

Ingredients to prepare: 1 cup of water; a pinch of salt; 1 raw egg; 1 glass; 1 small tablespoon; 1 pair of chopsticks.

Experimental steps: 1. Prepare the experimental equipment.

2. Put the raw eggs into a cup with a certain amount of water, and observe the position of the eggs in the cup. (sink to the bottom of the water) 3. Gradually add salt to the cup, and when it is added to a certain extent, you will find that the egg rises slowly until it floats.

Experiment Description: The relative density (specific gravity) of raw eggs is greater than that of water, so they will sink.

Salt is slowly added to the water, the relative density of the brine is greater than that of the egg, and the egg will rise.

If water is added to the brine, the relative density becomes less and the eggs may sink to the bottom again.

Water, cup, salt, chopsticks, pour water into a cup, add salt, stir, and finally add eggs.

Hello, ordinary table salt is fine, but you need to put more of it.

Because the density of salt water is greater than that of eggs, salt water allows eggs to float up.2 Because the density of eggs is greater than that of fresh water, eggs will sink in fresh water, and the density of salt water is greater than that of eggs, so eggs can float in salt water.

The principle of making the egg float is that the buoyancy of the egg is large enough. You can add salt to change the specific gravity of the water, and when it reaches a certain amount, the eggs will float.

You can also directly change the liquid with a large gravity!

Here's how to make the egg float in the water and close it:Tools: water, eggs, drinking glasses, table salt, spoons.

1. Fill half a cup of water in a water cup and gently put the eggs into the water, usually the eggs will sink to the bottom of the water.

2. Put a spoonful of salt in the water, and you will find that the eggs slowly float up.

3. This is because after adding salt, the density of water increases, and the buoyancy of the egg is proportional to the density of water.

Precautions for making eggs float:1. If you see that the egg is floating in a suspended state, you can add more edible salt.

2. Raw eggs should be chosen, so that the effect of the test will be good.

3. If it is a boiled egg, you should add more edible salt to make the egg float.

Gravity and buoyancy, buoyancy is equal to the density of the liquid * g * volume of the egg, by adding salt to the water, increasing the density of the water, the egg will rise from the bottom of the water. 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; When the egg is immersed in salt water, its buoyancy is greater than the gravitational force, and the resultant force is upward, and the egg floats upward, and rises to a part of the volume to expose the liquid surface, and the buoyancy decreases to the same as the gravity, and the egg floats there.

Materials for experiments: large glasses, table salt, spoons, eggs.

Step 1: Pick up the kettle, pour half a glass of water, then put the egg in the water, and the egg will slowly sink into the cup or stay at the bottom.

Step 2: Put 5 spoons of salt in a row, the egg floats up slightly, and put 3 spoons of salt in a row, the egg changes from lying horizontally to standing upright, and the area touching the bottom of the cup becomes smaller.

Step 3: Take out the eggs from the stove, stir the salt water with chopsticks, the salt at the bottom of the cup is basically melted, and then put the eggs in, the eggs keep floating up and down, and they will be messy for a while, and they will not move in the middle of the cup of water.

Step 4: Add 3 more tablespoons of salt, the egg gradually rises to the surface of the water, the top of the egg occasionally emerges from the water, press the egg down with your fingers, release your fingers, and the egg returns to the water.
