Question

Describe any two applications of pressure.

Answer 1

Two applications of pressure are

• Syringes – They are used to draw out blood from vessels during blood tests. Due to the pressure of blood, which is a liquid, it moves into the syringe when the plunger is withdrawn.
• Vacuum cleaner – It is a machine used for cleaning purposes. It has a fan inside, which creates low pressure inside the machine. This results in the air and dust particles getting sucked into the device.
