Question 8
Wear safety goggles. Connect two transparent syringes of the same size with plastic tubing, without gaps. Partly fill one syringe with water, remove air bubbles, and leave a space between its piston and the water. Raise the empty syringe's piston to leave space inside. Hold both outlets downwards, with the water-filled syringe lower than the empty one. Press the empty syringe's piston down slowly and steadily. Observe the other piston. Place a lightweight object on the water-filled syringe's piston and continue pressing.
What happened to the water-filled syringe when you pressed down on the empty syringe's piston? Give a reason for your answer.
