*target # 5- identify and explain the changes that occur with temperature and pressure. (using the 5 laws and principles) pgs - 63-69

1. what scientific rule describes why water squirts from a plastic bottle when it’s squeezed?
2. if an object floats, the volume of displaced water is equal to the volume of _____________.

Explanation:

Question 27

The scientific rule here is Pascal's Principle. Pascal's Principle states that a pressure change applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container. When a plastic bottle (enclosing water, a fluid) is squeezed, pressure is applied to the water. This pressure is transmitted, and since the bottle has an opening (like a hole), the water squirts out as the pressure forces it through the opening.

According to Archimedes' Principle, when an object floats in a fluid (like water), the volume of the displaced water is equal to the volume of the submerged part of the object. For a floating object, the buoyant force equals the weight of the object, and the volume of displaced water corresponds to the volume of the object that is under the water's surface (submerged volume).

Answer:

Pascal's Principle
