In an osmosis experiment, a visking tubing filled with concentrated sugar solution is placed in a beaker of distilled water. The visking tubing acts as a partially permeable membrane. Which statement describes what happens and why the liquid level in the tubing changes?
- Water enters the tubing by osmosis so the liquid level inside rises.
- Water leaves the tubing by osmosis so the liquid level inside falls.
- Sugar diffuses into the beaker so the liquid level inside rises.
- Sugar diffuses into the beaker so the liquid level inside falls.
