Penggunaan Botol kaca sebagai tekanan udara dalam dan interaksi dengan tekanan atmosphere akan menyebabkan penomena tekanan yang menarik bagi siswa

1. Tekanan udara dengan air
Dadan Sumardani

2. Today we gonna talk about “Magic Presure”

3. Procedure
• Firstly, We will try the Bottle without water,
• Then, put the card in the mouth of glass. And flip it.
Let see what happen,
• The card fall because no different pressure inside the bottle and
outside the bottle

6. Tekanan Udara Dengan air
• If we fill water into a bottle, then the bottle is closed and the glass is turned over, the water in the glass
does not spill. This happens because of the application of the law of pressure.
• This is due to the free air pressure pressing on the paper.
• The air pressure outside the glass is greater than the water pressure inside the glass.

7. The air pressure from outside the bottle is responsible for
keeping the card stuck in the mouth of the bottle
