Heat vinegar and oil

Oil and vinegar are common condiments in our daily life. No delicious dish can be made without oil. There are many kinds of oil, such as soybean oil, olive oil, corn oil and peanut oil. Dishes made with different types of oil have different tastes. Vinegar is a must-have for making cold dishes, such as spinach and peanuts with aged vinegar. Vinegar can also be used to make some hot dishes, such as hot and sour shredded potatoes. Heat the oil and vinegar together and adjust them to a certain ratio so that you won't get hurt if you put your hands in the oil.

First, boil soybean oil and vinegar together. The temperature at this time is only 60 to 70 degrees, because the boiling point of vinegar is very low and does not exceed 100 degrees Celsius. After the two are boiled and cooled, the soybean oil will always float on top of the vinegar due to its lower density, making it easy to separate.

The method of separating oil and vinegar is as follows:

The density of vinegar and oil is different. The density of vinegar is 1.05kg/L, and the density of cooking oil is generally 0.8kg/L. When the two are mixed in a container and left to stand, they will separate into layers, with the oil on the upper layer and the vinegar on the lower layer. A separatory funnel can be used to separate them. The easiest way at home is to pour out the oil, and what is left is the vinegar.

Mercury has a very tight molecular structure and is not easy to evaporate or react chemically. When water, oil or vinegar are added to mercury, no violent reaction will be seen in the short term. The current situation is that grease floats on the water-vinegar mixture, and the water-vinegar mixture adheres to the mercury. In their relationship, mercury is the heaviest and is at the bottom, followed by a water-vinegar mixture in the middle, and oil and fat is the lightest and occupies the top.

Olive oil is not used for washing hair but for hair care. Olive oil makes your hair look like clouds. If a young woman has beautiful hair, it can add a bit of charm and make her look more lively and lovely. After shampooing, pour a small amount of warm water into the basin and add some olive oil (depending on the amount of hair and its health). Gently rub it into the hair directly from the palm of your hand. Regular use can make hair soft, smooth and beautiful, prevent dryness, hair loss and reduce dandruff. Rub your head with olive oil, which can be absorbed by the scalp and hair.

Don't use pure vinegar to wash, dilute 3 spoons of vinegar with water. Also, use shampoo to clean the oil stains in your hair before using vinegar. I have tried two methods: 1. Apply essence first, then wash and then pour vinegar water to wash, 2. Use vinegar water first and then pour essence.
