Sink to float up, why do some objects float up and some objects sink down

Of course, this sentence is very true, there is a cause to have an effect, if it does not sink, how can it float up? If there is no beginning, how can there be results?

A lot of things have happened lately that put yourself in a state of anxiety. There was an opportunity for a state-owned enterprise before, and after thinking about it for a few days, I decided to go over, but I made a mistake and finally gave up on my own. In the days that followed, I often regretted and felt like I had made a wrong decision.

However, the path you choose must be completed on your knees. Fortunately, I am still young, and there is a broader world for me to explore, and there is no need to limit myself to state-owned enterprises or the system.

This incident made me understand that in the case of impetuousness, don't make any decisions, and don't rush to call your friends, you must calm down first and let yourself be at peace, otherwise, when you make a wrong decision, it will be too late to regret it.

Maybe it's because I haven't experienced many things, and my thinking is not mature enough, so what I do is a bit unreliable. However, eat a trench and grow wise, summarize things in time, and correct your mistakes in time. In this process, you can listen to other people's opinions, but remember, don't care about other people's opinions, think about what your heart wants most, what you desire the most, and also, when making decisions, think about what your original intention is.

Sink to float up. Life is a process of accumulation, the more people with stories, the more simple they are, and the more superficial and thin people are, the more impatient they are. I hope that in my later life, I can calm down to do things and make decisions.

You must stick to the decisions you have made, and you can't retreat when you encounter trouble at the beginning.

If the weight is not enough, put a little more water in the upside-down bottle, so that the outer bottle will sink if you pinch it gently.

Float sinker principle.

According to Pascal's law, when the air is compressed, the pressure is transferred to the water, the water is pressed into the bottle, the air in the bottle is compressed, and then some water enters the floating sinker, the drainage volume remains the same, and the gravity is greater than the buoyancy it is subjected to, so it sinks downward. When the bottle is released, the volume of air on the water surface inside the cylinder increases, and the pressure decreases.

The compressed air in the floater presses the water out, and the drainage volume increases, and the gravity of the floater is less than the buoyancy it is subjected to, so it floats upward. The float and sink of the floater is achieved by changing its drainage volume under the action of external pressure. There are various forms of floating sinker experiments.

Generally, the volume of gas inside the float sink is changed through the change of external pressure, so as to achieve the purpose of controlling its sinking and floating.

A float sinker is an instrument used to demonstrate the buoyancy of a liquid, the compressibility of a gas, and the transfer of pressure from a liquid. It is a small glass bottle with a small hole at the lower end, through which water can enter and exit the bottle. Put it in a high water tank and let it float on the water.

Cover the mouth of the cylinder with a thin beam leakage rubber film and tie it tightly, press the rubber film with your hands, and the water and air in the cylinder are in a closed container. According to Pascal's law, when the air is compressed, the pressure is transferred to the water, and the water is pressed into the bottle, and the air in the bottle is compressed. When the hand leaves the rubber film, the volume of air on the water surface in the cylinder increases, the pressure decreases, and the compressed air in the floater presses the water out, and the gravity of the floater is less than the buoyancy of the air match, so it floats upward.

When the hand exerts the right amount of pressure on the rubber sheet, the floater floats at any depth in the water.

This is a physical phenomenon: an object immersed in a liquid is subjected to the buoyant force of the liquid on it, and the buoyancy force is equal to the weight of the liquid that it displaces (occupies) the same volume as itself, and when the weight of the liquid it displaces is greater than its own weight, it floats; When the weight of the discharged liquid is less than its own weight, that is, when the buoyancy is less than its own weight, the object sinks underneath; If the two are equal, the object can remain in the position of the person inside the liquid.

Tying a dense weight underneath the object can sink the object floating on the water.

Tying a less dense hollow object to the object allows the sinking object to float up.

The floating salt water sank, and the sinking made it larger.
