Worked Solution

Step 1: Identify the action (pushing plunger). Step 2: Relate the ability to push the plunger to the property of compressibility. Step 3: Gases (air) can be compressed because their particles have space between them, while liquids (water) cannot. Step 4: Final Answer: Air can be compressed but water cannot.

Correct answer: Air can be compressed but water cannot.
