Question

Give me an introduction of a project called Five experiments.

The experiments are- Air occupies space,Solids have definite shape,To show that liquids have large intermolecular space,Melting of wax is a physical change and Sublimation of ammonium chloeide is a physical change.

Answer 1

Air occupies space
Things needed
A bathing mug
A bucket
Water
Method
Take the bucket and fill it with water then take the the mug and push it towards the bucket filled with water don' t tilt the mug and then check it with a tissue after checking
tilt the bucket
Observation
We can see huge bubbles coming up
Conclusion
It is because the mug which is pushed inside is filled with air so when we tilt the mug the air comes out in the form of bubbles if we don't tilt the mug after taking it out of the bucket filled with water the mug will not be wet that is because the air is filled in the mug
By this activity we get to know that air occupies space
