1, melted with salt water. When it snows in winter, people often see snow removal machines or artificial snow removal on the road, and generally sprinkle salt on the road. When salt and snow are mixed together, it becomes salt water. The characteristic of salt water is that its freezing point is lower than that of ordinary water, and it will not freeze at the same low temperature, thus further melting the surrounding snow and having the same effect on the ice on the ground. Thawing frozen fish with salt makes use of this principle. The method is simple, that is, thaw the fish in salt water. It takes about 10 minutes for fish that are badly frozen, and 5 minutes for fish that are not badly frozen.
2, use vinegar bubble, here the principle of vinegar and salt is somewhat close, vinegar contains acetic acid, and the acidity of acetic acid is stronger than other acidic substances. Mixing with water can also lower the freezing point of water. It takes a long time to thaw the fish with vinegar here, but it also has its advantages, that is, it can remove the fishy smell and peculiar smell of the fish at the same time of thawing. The method is also very simple, just pour a few spoonfuls of vinegar into the water and put the fish in. It takes about 20 minutes to thaw the fish with vinegar.
