Answer:
AIM:
To show that air exerts pressure.
MATERIALS REQUIRED:
Plastic bottle, hot and cold water
PROCEDURE:
1) Take a soft plastic bottle.
2) Fill it half with hot water.
3) Empty it and immediately cap the bottle tightly.
4) Now pour Ice cold water over the bottle.
OBSERVATIONS:
The plastic bottle gets deformed when the cold water is poured over it.
CONCLUSION:
When we fill the bottle with hot water and empty it, the air inside the bottle becomes hot.
When cold water is poured over it this hot air becomes cold and pressure inside the water decreases.
The pressure of air outside being higher, crushes the bottle.
