A hydrogen-inflated polythene balloon is released from the surface of the earth. As the balloon rises to an altitude up in the atmosphere, it will
- a)decrease in size
- b)flatten into a disc-like shape
- c)maintain the same size and shape
- d)increase in size
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A hydrogen-inflated polythene balloon is released from the surface of ...
As a hydrogen-inflated polythene balloon rises to an altitude in the atmosphere, it will increase in size. This is because the atmospheric pressure decreases with increasing altitude. As the balloon ascends, the external pressure decreases while the pressure inside the balloon remains relatively constant

A hydrogen-inflated polythene balloon is released from the surface of ...
Answer:
Introduction:
When a hydrogen-inflated polythene balloon is released from the surface of the Earth and rises to an altitude in the atmosphere, it will maintain the same size and shape (option D). This can be explained by understanding the properties of gases, the behavior of balloons, and the concept of buoyancy.
Properties of Gases:
- Gases are highly compressible, meaning their volume can change significantly with changes in pressure.
- Gases expand to fill the entire available space.
Behavior of Balloons:
- When a balloon is filled with hydrogen gas, the gas expands to fill the volume of the balloon.
- The pressure inside the balloon is equal to the atmospheric pressure outside the balloon.
- The buoyancy force exerted on the balloon is equal to the weight of the air displaced by the balloon.
Explanation:
As the hydrogen-inflated polythene balloon rises to an altitude in the atmosphere, the atmospheric pressure decreases. However, the pressure inside the balloon remains constant because the gas inside the balloon is in equilibrium with the atmospheric pressure. This means that the balloon will maintain the same size and shape.
Pressure Change:
- As the balloon rises, the atmospheric pressure decreases due to the decreasing density of air at higher altitudes.
- The pressure inside the balloon remains constant because the gas inside the balloon is in equilibrium with the atmospheric pressure.
- The pressure inside the balloon is equal to the atmospheric pressure outside the balloon at any given altitude.
Buoyancy Force:
- The buoyancy force exerted on the balloon is equal to the weight of the air displaced by the balloon.
- As the balloon rises, the density of air decreases, but the volume of the balloon remains constant.
- The weight of the air displaced by the balloon decreases with increasing altitude, but the buoyancy force remains the same.
Conclusion:
Based on the properties of gases, the behavior of balloons, and the concept of buoyancy, a hydrogen-inflated polythene balloon released from the surface of the Earth will maintain the same size and shape as it rises to an altitude in the atmosphere. The pressure inside the balloon remains constant, and the buoyancy force exerted on the balloon remains the same.
