If a balloon filled with air is sent to moon, what would happen?

Options

A. The balloon expands because the atmospheric pressure of the moon is slightly lower than that of earth.
B. The balloon bursts because the atmospheric of the moon is much lower than that of earth.
C. The balloon contracts because the atmospheric pressure of the moon is much lower than that of earth.
D. No change is observed because change of atmospheric pressure has no effect on the balloon.

Answer

### Step-by-Step Solution:

1. **Understanding the Environment**: The moon has a very thin atmosphere, which means it has much lower atmospheric pressure compared to Earth.

**Hint**: Think about how pressure affects objects in different environments.

2. **Effect on the Balloon**: When a balloon filled with air is taken to the moon, the lack of external pressure allows the air inside the balloon to expand.

**Hint**: Consider what happens to gases when external pressure decreases.

3. **Expansion of the Balloon**: As the balloon rises in altitude (in this case, to the moon), the air inside it tries to occupy more space because the external pressure is low.

**Hint**: Remember that gases expand when there is less pressure acting on them.

4. **Breaking Point**: The balloon will continue to expand until it reaches its breaking point, which is the maximum stress that the material of the balloon can withstand.

**Hint**: Think about the limits of materials and what happens when they are stretched too far.

5. **Outcome**: Eventually, the balloon will burst due to the excessive expansion caused by the low atmospheric pressure on the moon.

**Hint**: Visualize the process of a balloon being inflated and what happens when it cannot hold any more air.

### Final Conclusion:
When a balloon filled with air is sent to the moon, it will expand due to the lack of external pressure and will eventually burst when it reaches its breaking stress.
