Answer 1

Surface tension to the water molecule. There is air in the bubble.

Answer 2

Not all time True!

When you store water it's normal to have bubbles formed by the air particles, which cling to the surface of the inner wall of your container.

Since the density of water is comparatively higher than boiled water, those air bubbles if formed release itself easily outward!

I'm not sure abt your filtering process!

but, you can see Bubbles when you boil water, it's jus because the air particles present hidden in between the molecules of water will be discharged and grouped to form bubbles that too comes to the surface of the water and burst-out when you continue boiling!

Water by losing it's density makes bubbles to move easier..! Inturn by losing air content water becomes less denser!

Answer 3

Water has oxygen particles in it, particularly when it comes out of a tap, because has lots of air mixed in with it as it travels through the pipes.

After you boil water, it becomes depleted in oxygen, which is why there aren't as many bubbles.

Answer 4

well the fact is that the water have oxygen and also air in it so may the water had run and captured some oxyge/air that later becomes those bubbles that you see

Answer 5

hi medilda this is becoz fo the surface tension fo the water.

Answer 6

b'coz water really having air bubble(oxygen in it)
