If you put it in water, it will sink, and if you put it in salt water, it will float on the surface.

After cleaning, the original concentrated salt water will still float on the surface, and it will sink in the clean water.

Why: In junior high school, you learn about density and buoyancy.

The density of salt water is greater than that of water, according to the buoyancy formula f float = density * v row * g (10n kg), when v row is unchanged, the buoyancy is proportional to the density, so the greater the density, the greater the buoyancy, and when the buoyancy is greater than the gravity of the egg, it will not sink. (g doesn't care about it because it's a fixed value).

1。The eggs flutter in the cup of concentrated salt water, and the eggs sink in the cup of clear water;

Mountaineering revelations.

I have been to Mount Tai once before, it was a late autumn, during the holiday, and my father and mother traveled to Mount Tai, the eldest of the five mountains, and what happened on that mountain is still unforgettable to me.

At the foot of the mountain, looking at Mount Tai, which is a majestic purpose, I can't help but forget and be afraid: it was out of reach for me at that time. When my father saw me with such an expression, he hurriedly gave me a reassurance:

Think about the beauty of the infinite scenery if you climb up. Believe in yourself: 'I' can do it!

Dad had a smile full of confidence in me on his face, patted me on the shoulder, looked at Dad's meaningful eyes, and then looked at the majestic Mount Tai, I seemed to realize something, I closed my eyes tightly, and shouted: "I'm out of the way!" He quickly stepped onto the bluestone path leading to the top of the mountain.

The adults told me to eat something before leaving, but I quickly stuffed a loaf of bread into my mouth, and then destroyed it again with great speed, and then hurriedly started the "Silk Road", although the trail was too long for me, and I experienced many, many sights, but I still wanted to walk the whole ...... as soon as possibleFinally, after walking the whole way before the sun sets, standing on the top of Mount Tai, I saw the beautiful scenery like poetry: the green meadow like Pei Cui; A tall and delicate tree like a sentinel; Gorgeous flowers like shy little girls; white and soft white clouds like flowers; the sun, which is as rosy and shiny as a marquee; As ......Intertwined, forming a wonderful painting, together telling the beautiful scenery of the sunset, the second grade of primary school essay "Enlightenment Essay of Mount Tai".At this time, I was not only intoxicated by this beautiful and picturesque scenery, but most importantly:

I did it! I conquered the odds! I won the event!

Looking at my dad standing by the side, I gave him the most smug smile, and he was proud and proud of my victory.

People have experienced many difficulties in their lives. Ups and downs, but only by facing difficulties, facing difficulties, overcoming difficulties can we achieve the ultimate victory, people's life is like that bluestone path, and many difficulties in life are like my kind of fear in my heart, only by overcoming that kind of heart, can I reach the peak, isn't this the same truth.
