Question

To which scientific principle does the described experiment relate, where fluid is pulled into a straw and the tip is closed to create a vacuum effect?

a) Archimedes' Principle
b) Torricelli's Principle
c) Boyle's Law
d) Newton's Third Law

Answer 1

The described experiment where a fluid is drawn into a straw and the tip is closed to create a vacuum effect is related to Archimedes' Principle.

Step-by-step explanation:

The experiment described, where fluid is pulled into a straw and the tip is closed to create a vacuum effect, relates to Archimedes' Principle. This principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid that the object displaces, and is involved whenever an object interacts with fluid.

However, other principles like capillary action or cohesion and adhesion also play a role when a fluid is moving in narrow spaces or against gravity.
