Drag the icons from the bank below to label each scenario with the change in the volume of the balloon. Change in pressure P, increases, Pa decreases P, increases, P constant Pn increases, P increases P, constant, P increases P, constant, P, decreases Change in volume Legend Need more information ?? Balloon volume decreases Balloon volume increases t P decreases, P constant P, decreases, P. decreases e to search

Explanation / Answer

1. Pin increases Pout decreases - the volume increases

This is because the air in balloon increases but the pressure outside decreases which means the balloon can expand freely.

2. Pin increases Pout constant - volume increases

Pin increase is due to increase in air volume inside the balloon. Since Pout is constant, the balloon expands.

3. Pin increases Pout increases - volume increases

A balloon can withstand pressure and the pressure inside will be more initially. However after sometime, the balloon will burst.

4. Pin constant Pout increases - volume decreases

As pressure outside increases and there's no change in pressure inside, the air move out or the balloon bursts.

5. Pin constant Pout decreases- volume decreases

The difference in pressure causes air to move out.

6. Pin decreases, Pout increases- volume decreases

Here pressure from outside is more, hence the air is forced to move out.

7. Pin decreases Pout constant - volume decreases

As pressure decreases, volume decreases.

8. Pin decreases Pout decreases - volume decreases

As Pin decreases, the volume decreases because the pressure outside is always lesser than the pressure inside.
