Question

When did you observe that the air inside seemed to become foggy? 2. When does this fog disappear? 3. When is the pressure inside the bottle higher? 4. Is the fog observed when the pressure in the bottle is high or when it is low? 5. What is the need for smoke particles inside the bottle for this experiment? 6. What might happen if you do the experiment without the smoke from the incense stick? Now try it and check if the prediction was correct. What might be happening in the above experiment in the absence of smoke particles?

Answer 1

1.when water molecules condense

Answer 2

Answer:

When the air inside the bottle is saturated with water vapour and the smoke of the incense stick is inserted in it.The smoke particles acts as a nucleus for the water vapours and thus cloud formation takes place.

1) When the bottle is released.

2)When these droplets will become heavier they will come down as a water and thus fog will disappear.

3)When pressure is high it causes

condensed droplets to come down thus disappearing fog.

4) The fog is observed inside the bottle if the pressure inside the bottle is low. 5)They act as nucleus around which water droplets are formed 6) Particles of water will not be visible as

bigger droplets will be hard to form.
