The following are the relevant contents of several frost-making experiments: ** 1. Dry Ice Frost Experiment ** 1. ** Material preparation ** - Dry ice, cut cans, disposable cups, thermos flasks. 2. ** Experiment Steps ** - He poured the dry ice into the can, then covered the lid and observed the outer wall of the can. In about a minute, a frosty substance would appear on the outer wall of the can. 3. ** Experiment Principle ** - Through this experiment, one could explore the source of frost formation. Some students would think that frost was transformed from dry ice, while others would think that it was transformed from water vapor in the air. He could touch the "frost" on the outer wall with his hand and found that the "frost" had turned into "water", which proved that the "frost" was directly transformed from the water vapor in the air when it was cold. ** 2. Frost Experiment with Ice and Salt (Iron Cup Version)** 1. ** Material preparation ** - Water, an iron cup filled with ice cubes, and salt. 2. ** Experiment Steps ** - The ice cubes in the iron cup were covered with salt to accelerate the melting of the ice cubes. - He poured the water from the cup into the iron cup. - After waiting for a few minutes, frost could be observed. 3. ** Experiment Principle ** - As the surface temperature of the iron cup with ice cubes was very low, the temperature of the air near the surface of the iron cup was relatively high. When there was a temperature difference between the air and the surface of the iron cup, the air would cool down when the warmer air came into contact with the colder surface of the iron cup. When the water vapor was saturated, the excess water vapor would be separated out. If the temperature was below 0°C, the excess water vapor would condense into ice crystals on the surface of the object, which was frost. ** 3. Frost experiment with ice and salt (stainless steel basin version)** 1. ** Material preparation ** - Ice cubes, stainless steel basin, salt, towel. 2. ** Experiment Steps ** - Put the ice cubes into a stainless steel basin and add salt to make them melt quickly (the principle is the same as snow melting agent). - During this process, the outer wall of the bottom of the stainless steel basin quickly cooled down, and the evaporated water vapor on the towel directly turned from gas to solid, condensing on the outer wall of the stainless steel to form "frost." The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
The following is a description of some of the operations related to shaving: - When Mr. Zhou shaved, he mentioned that the beard on the upper lip and chin was more difficult to deal with. When shaving the upper lip, he had to use the gap between his fingers to shave it clean, otherwise there might be residue at the root. When shaving the chin, he had to pull it with the thumb of his left hand. The knife in his right hand followed the thumb, and his left hand cooperated with his right hand. Because the beard on the chin was not easy to be still, more skills were needed when shaving. - When scraping the corner of the eye, if the eye mucus is obvious, after the eyelid is scraped, the eyelid can be opened and the knife can be used to remove the eye mucus. For the case where the hair at the corner of the eye is heavy, if you want to do a fine job, you can handle it. There is also the treatment of eye mucus in different positions around the corner of the eye. For example, if there is eye mucus at the corner of the eye in the eyebrow, the knife can be used to deal with it similar to the eyebrow. Pay attention to the distance between the positions, etc. However, there was currently no complete video tutorial for shaving. If you need a more detailed and accurate shaving video tutorial, it was recommended to search for a specialized shaving tutorial video through a search engine.
