What is the state of the foam of the bath gel, and how to make the foam in the bath

It does not belong to the gaseous or liquid state of natural and one. The bath itself is in a liquid state, and it is still liquid when it is foamed. The same goes for air

It's a mixed substance, and I forgot what it's called.

The explanation is as follows: in order for a substance to undergo biological changes, several conditions must be met. Except for evaporation and sublimation, which can occur at any temperature, the other changes are either endothermic or exothermic (these two are also endothermic, but there is no need for a temperature difference) and when you turn the bath into foam, there is no event that can cause biological changes, that is, the foam or the bath is essentially a liquid.

It's just that air is mixed in with the foam, so it's like this.

It is a mixture of air and liquid foam. This state can be learned in Chapter 2 of Chemistry Module 1 of the new curriculum standard. If we talk about using physical knowledge, we mainly use thermal part of the knowledge:

A system of dispersions formed by the dispersion of insoluble gases in liquids or molten solids. The linear size of its volume is more than 10-5 cm. Its shape often varies depending on the environment.

For example, soap foam, beer foam, etc. are all dispersions of gases dispersed in liquids. For example, foam plastic, foam rubber, foam glass, etc. are all dispersed systems of gas dispersed in molten solids, which are obtained by cooling. Gathered together to form.

Liquid. It's just a liquid state with air injection.

And cola is a truth.

The content of the shower gel is determined by the ability of a surfactant to resist hard water.

And combined with oil deposition technology, then there is a foam, resulting in a smooth and skin-friendly feel.

It's not that you can't rinse it clean, so don't worry about it.

However, it is still necessary to rinse off when using body wash.

In addition to surfactants and moisturizers, shower gels also contain chemical ingredients such as antiseptic and bacteriostatic agents, i.e., fragrances.

These preservatives can cause eczema and allergies, and if you don't rinse cleanly, it is easy to cause itching, rashes and other problems.

It is recommended that when choosing a shower gel, you can:

1. Check whether the package is complete, too long exposure time in the air will affect the change of its composition.

2. Determine the shower gel you choose according to your own allergens, and strictly choose the ingredients of the purchased products.

3. Choose products that are suitable for you to ensure the healthy quality of your life.

You can have bubbles with shower gel or soap with bath flowers, and the effect shown on TV is to buy a bath that produces a lot of bubbles.

Wet the water with a bath bomb and gently rub it to produce a rich lather.

There are three types of shower gels::

1.Surfactant form: It is mainly composed of surfactants with washing effect, which is mild and smooth. If the compound is not good, it is easy to have the feeling of not rinsing, which is an earlier shower gel;

2.Soap-based type: modified based on the principle of soap making, rich foam, easy to clean;

3.Surfactant and soap-based compound type: take the advantages of the two, rich foam, easy to rinse, and refreshing and moisturizing after washing. At present, there are more of the latter two types of shower gels on the market, so they also give people a different feeling of comfort.

It is a physical reaction, and the production of foam is due to surfactants, and the difference between physical and chemical changes mainly depends on whether new substances are generated.

Elite Changning Tianshan.

It is a physical change, and no new matter is generated.

It is a physical reaction, and the foam is produced because of the surfactant.

It is a physical reaction that produces oxidation.

This one is a physical reaction and there is no chemical change.
