from the balloon, explaing??? Plz tell in simple words

+ Q 5

Answer 1

Answer:

Balloons are made of rubber and they are permeable. Which means that there are very small holes and air can pass through them. It can even leak from the knot. The air pressure outside the balloon is very high and to match that the air molecules inside the balloon also move a lot, and in the process they collide with the wall of the balloon too and they can diffuse out.

Q5.

Diffusion - It is the movement of air particles from high concentration gradient to low concentration gradient, down the concentration gradient.

Brownian movement - It's the random movement of smoke particles or any other kind of particles in the air, which moves because of the air particle hitting them continuously and randomly
