Ice is transparent because from the microscopic world, the gaps between water molecules are very large enough to allow light to pass through.
There are two reasons for no breakage: 1. The container is not sealed, and the water expands after turning into ice, and the expanded part expands out of the mouth of the bottle. Offset a large part of the pressure. 2. The steel material is now strong for the number of ice.
A large amount of air dissolved in tap water, when the temperature drops, the dissolved air forms tiny bubbles that are frozen in the ice, so the freshly connected tap water appears white after freezing into ice. Mineral water is relatively transparent because it has been left for a long time before freezing, and most of the dissolved air has been released.
If it is a completely closed container with poor toughness, it will break, such as a closed plastic cylinder. (provided that the entire container is filled with water).

If you put the lid on, the lid may be inflated or the cup will break, and the mine tax will contain less air, so there are few small bubbles in the ice, and the ice is transparent, while tap water is the opposite. You can boil tap water and do experiments, the ice should be transparent, the statement of the first floor is wrong, who forms ice and the volume becomes larger should be the density of the ice is smaller. This is caused by the different arrangement of molecules.

Water freezes into ice, and it becomes larger because air enters it, and this is usually the reason why we see white ice. The reason for the answers to your two questions is the same.

Water expands when it turns into ice, regardless of whether it enters the gas or not. One of the reasons why the steel thermos will not break is that the expansion of the water in the cup is along the direction of the bottle body, which does not cause too much pressure on the bottle wall; Another reason is that metal is not easy to break because it stretches well.

Yes, but there are a few things to keep in mind:
1.Make sure the bottle is clean and free of any residue or odor.
2.Do not fill the bottle with water as the water will swell and if it is full, it will cause the bottle to deform or break. It's best to fill only a small amount of water to allow room for expansion.
3.Do not keep the Reiga bottle at the lowest temperature in the freezer compartment of the refrigerator, as too low a temperature will increase the risk of the bottle breaking. It is best to place it on top or in the middle of the refrigerator.
4.When you need to use ice, don't force the ice out of the bottle, as this may cause the bottle to deform or break. It is best to gently wipe the outside of the bottle with warm water to loosen the ice cube sock hall, and then gently pat the bottom of the bottle to let the ice slide out.
In conclusion, although it is convenient to use a mineral water bottle to make ice cubes, you need to be extra careful when using it to avoid bottle cracking or other accidents.
Boiled water or purified water Because they are soft water, there is no harm to the human body And pure water is hard water, which can be harmful if you drink it for a long time In recent years, with the change of people's consumption concepts and the enhancement of environmental awareness, mineral water, mineralized water, pure water, distilled water and space water have appeared on the market. Manufacturers of mineral water and mineralized water advertise that their drinks contain a variety of minerals needed by the human body, which can dispel diseases and strengthen the body, and are the best drinks; Some also claim that "mineral water is better than pure water, distilled water and space water, and these pure waters not only remove the harmful components of the human body, but also discard the beneficial components of the human body". Not to be outdone, the manufacturers of space water and pure water say that pure water has high purity, which is easy to dissolve food nutrients in water and be absorbed by the human body, and is easy to discharge harmful substances in the human body; Some even claim that "the human body does not need to absorb minerals from water, mineral water is harmful to the human body, and the biggest danger is the formation of stones". >>>More
