Question

Give reason , a) A balloon is being inflated . B) when an inflated balloon is immersed in water its size decreases . C) size of air bubbles raising from bottom of an aquarium increases

Answer 1

Answer:

A) Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

B) The pressure from the water causes the air to compress inside the balloon. The deeper the balloon is taken into the water, the greater the pressure, and therefore, the smaller the balloon will become.

C) As the bubbles move upwards, the pressure on them decreases. This causes increase in volume. So, as the bubbles move upwards, their size increases.
