Hydrostatic pressure and buoyancy | balloon under water
Questions:
- Can you inflate a balloon under water?
- What happens to the inflated balloon when it is pushed deep under water?
- What happens analogously to organs, e.g. the eardrum and the (air-filled) lungs?
Content taught:
- Inflating a balloon is also possible underwater. But: The hydrostatic pressure, i.e. the pressure that the water exerts on the balloon, makes inflation more difficult.
- If you push an already inflated balloon underwater, the volume of the balloon shrinks with increasing depth and the buoyancy decreases.
- Organs are also compressed analogously to the balloon with increasing water depth.
