Which device operates based on Pascal's law?

2. Which device operates based on Pascal's law?

1. A bicycle pump
2. A hairdryer
3. A microwave oven
4. A television

Answer: A) A bicycle pump

Explanation:

A bicycle pump operates based on Pascal's law. When you apply force to the pump handle, it compresses the air within the pump's cylinder. According to Pascal's law, this pressure is transmitted equally in all directions within the confined air, causing an increase in air pressure that allows you to inflate the bicycle tire.
