After school today, my mother took me to the market to buy food. By the way, I bought half a catty of eggs and bought two packets of salt, because I had to do a fun little experiment.
When I got home, I couldn't wait to take out two glasses and fill the water in both cups. One cup was water and the other cup was filled with two tablespoons of salt. Then I started to stir the salty water slowly with chopsticks, and the salt in the cup melted. I gently placed the eggs in a salted cup and the other egg in the salt-free water. At this time, the miracle appeared, and the eggs in the salt water cup floated up, but the eggs without the salt were still quietly sinking to the bottom. What is going on here! I checked the computer. The salt water is denser than water. The salt concentration is proportional to its density. When the salt water density reaches the egg density, the eggs will float.
did this experiment and made me understand that when the egg is placed in a salted cup, the egg will sink without buoyancy. I will often do some small experiments that are both fun and insightful in the future, because it is not only interesting, but also makes me feel the brain.
