Is it better to be hollow or solid? What is the difference between gold hollow and solid?

Generally speaking, it is solid, and if it is better to be solid, if it is said to be a dish, it must be solid.

Is it better to be hollow or solid? What does this look like? Because you need to be hollow inside, if you use it, it is good to be hollow, and if you need to be solid, it will be solid.

When we buy feng shui hyacinth, we will find a problem, that is, the gourd ornaments are divided into two styles: open hollow and non-open solid, so which style has a better effect? In fact, the two kinds of gourds do not have a high or low function.

It depends on what it is, if it's a person or a bed or something, it's best to use a solid one.

Personally, I think that solid is more solid, more stable, and better than hollow.

Whether the air is better or quartz depends on which one you use it for, but if you use it for the wall, I think it's better to be solid.

In general, it depends on what kind of needs you have, some may be better hollow, but specifically, it may be better to be solid.

What to buy? Just look at Ha, if you are a man, it is solid and good. If it is to buy this hollow of bamboo, it is good.

Is it better to be hollow or solid? I think it's definitely solid.

Hollow and solid objects cannot be too accurately judged which is better, this mainly depends on which aspect the object is used for.

Actually, it doesn't matter, but I think the first one might be better.

The southeast is solid and relatively good.

This is still yours, do I think it can be realized? One side of the water spinach comparison.

Well, I'm especially glad for your question, I personally think it's better to be hollow, it's better to look good, and it's more practical.

Is it better to be hollow or solid, I think it is good to have four of both, the key to your own benefits is that you look at what he uses it to know what purpose is good.

It can be judged by mass, Liwu density and volume!

For example: if the mass of an aluminum ball is 540g and the volume is 300cm 3, judge whether it is solid or hollow?

Method 1: Judge by quality:

Root confession m=pv=>540g

The mass is less, so the ball is hollow which front or!

And the volume of the hollow is: v empty = (810g-540g) Method 2: Judge by density:

According to p=mv=540g 300cm3="The density is less than that of aluminum, so the ball is hollow!"

Method 3: Judge by volume:

According to v=m p=540g <300cm3 volume ratio is smaller, it means that it is hollow!

First, the hollow ** jewelry is the use of the ductility of the **, and the outside of the jewelry is relatively large. If you buy by the gram, the **jewelry** of the same size, the ** hollow **jewelry is relatively low. The biggest advantage of hollow ** jewelry is that the ** jewelry of the same size, the hollow ** is low, and there is a row of faces when worn.

However, because it is hollow in front of the foundation cave, there is no support inside, and if it encounters an impact or collision, the jewelry will be flattened and deformed, and it is difficult to repair.

Second, the solid ** jewelry is more real, the jewelry inside and outside are **, heavier, the biggest advantage is firm, it is not easy to break or deform during wearing, wear for a long time, ** jewelry will not be out of shape. If you buy by the gram, the solid jewelry will be more expensive than the hollow jewelry, and it will be slightly heavier to wear multiple solid jewelry at the same time.

There are three ways to <>:

1. Treat the object as solid, multiply the density of the matter that makes up the object by the volume of the object, and obtain the mass of the solid object, if the mass of the solid object is greater than the mass of the object itself, then the object is hollow, and if the mass of the solid object is less than the mass of the object itself, it is solid.

2. Divide the mass of the substance by the density of the substance to obtain the volume of the solid part, if the volume of the solid part is less than the volume of the object, then the object is hollow, if the volume of the solid permeable part is greater than the volume of the object, it is solid.

3. Divide the mass of an object by the volume of the object to obtain the density of the object, if the density of the object is less than the density of the matter that makes up the object, the object is hollow, if the density of the object.

The hollow has a small density, a large volume and a light weight

The way to judge a solid or a hollow is to divide the mass of this object by its volume, if it is equal to the density of this substance, then it is solid, if it is less than the density of this substance, then it is hollow

Aluminum, iron, copper.

Since the three balls have equal masses and unequal densities, their solid volumes are certainly unequal. And because the denser the object at the same mass, the smaller the volume, so their solid volume is arranged from small to large, copper.

Iron. Aluminium. However, the three balls are the same volume, indicating that the balls are not solid. The smaller the solid volume, the larger the hollow volume. So in the end the answer is aluminum, iron, copper.

A neat trick to this problem is to remember that if you compare the same mass with the same volume, the denser the hollow volume, the larger the volume. I hope the landlord figured it out. ：）
