这个物理实验是关于压强的,拿一个水杯,装3/4的水,然后在杯上用一张纸盖住,把它翻转过来,纸不掉下来,这说明外面的大气压与内部的大气压相同.

这个物理实验是关于压强的,拿一个水杯,装3/4的水,然后在杯上用一张纸盖住,把它翻转过来,纸不掉下来,这说明外面的大气压与内部的大气压相同.
这个物理实验是关于压强的,
拿一个水杯,装3/4的水,然后在杯上用一张纸盖住,把它翻转过来,纸不掉下来,这说明外面的大气压与内部的大气压相同.

Take a cup,fill three quarter of it with water,cover the cup with a piece of paper,then turn it over.the paper will not fall.this shows that the atmospheric pressure outside and inside of the cup is the same.
This is a physics experiment on the pressure,
Take a glass, put 3 / 4 of the water, and then in the cup on the cover with a piece of paper, flip it over, can not paper over, This shows that the atmospheric pressure outside and within the same atmospheric pressure.
This ia a physical experiment on pressure.
First,you should take out a glass and fill up three forths of it with water.
Then,you should cover it with a piece of paper and turn it over.
As a result,the paper will not fall.
It shows that the pressure outside is the same as it inside.
