Question

A balloon stops rising up beyond a particular height when the density of as inside the balloon:
(A) exceeds the density of air outside
(B) equal the density of air
(D) none of these above
(C) becomes less than the density of air​

Answer 1

Answer:

B

Explanation:

things having same density remain at same level

Answer 2

The correct answer is when the density of the air inside the balloon equals the density of air (option B).

• The main factor that makes the balloon rise is the density it possesses.
• The balloons are filled with gases that have a lower density than atmospheric gases.
• This difference in density causes balloons to ascend above the atmosphere.
• But as we move at a higher altitude, the density of air starts decreasing as atmospheric pressure decreases.
• There will be a point in the atmosphere where the density of the atmosphere equalizes with the density of gas inside the balloon.
• As a result, the balloon will come to a halt since there will be no density difference.
