Question

Explain why a gas bubble released at the bottom of a lake grows in size as it rises to the surface of the lake

Answer 1

Explanation:

A glass bubble realised at the bottom of a lake grows in size as it rises to the surface of the lakes because pressure decrease continuously when it go up in water.At any point under the surface of liquid pressure in proportional to this depth

Explain why a gas bubble released at the bottom of a lake grows in size as it rises to the surface of the lake.

                                                 

║⊕ANSWER⊕║

• At the bottom of a lake, Pressure increases.

Total pressure = Atmospheric pressure + Pressure due to water column

According to Boyle's law

PV = constant

• Volume of bubble increases due to decrease in pressure as it rises towards the surface.

• Volume increases due to expansion of air molecules inside the bubble.
