Final answer:

Pressure is force per unit area and has various daily life applications. Liquids exert pressure through flowing out of a hole. Applications of liquids include hydraulics and water distribution systems.


Explanation:

Pressure is the amount of force exerted per unit area and is essential in various daily life scenarios. Three applications include:

  1. Using a syringe to administer medicine (application of pressure to push the liquid through the needle).
  2. Car brakes (applying pressure to stop the vehicle).
  3. Blowing up a balloon (using pressure to inflate it).

One way to observe that liquid exerts pressure is by noting that liquid can flow out of a small hole in a container due to the pressure it exerts.

Two applications of liquids are in hydraulics systems (using liquids to transfer power) and in water distribution systems (using liquids to transport water).
