Pressure and Pascal's Principle

Diagram shows a hydraulic jack. What is the characteristics of the oil that allows the above instruments to lift the car while we change the car tyres?

• Oil cannot be compressed

• Oil has a fixed shape

• Oil has particles that are closely arranged and compact

• Oil has particles that are arranged far apart from each other

what was pascals principle best known for?

• pressure

• density

• volume

• mass

This Law states: Pressure exerted on a contained fluid is transmitted undiminished in all directions in the fluid and perpendicular to the walls of the container

• Work Law

• Joules's Law

• Pascal's Law

• Miss Shankowski's Law

What is the fundamental principle of Pascal's Law?

• Pressure applied to a confined fluid is transmitted equally in all directions

• Pressure decreases with depth in a fluid

• Pressure is inversely proportional to volume

• Pressure is directly proportional to temperature

What happens to the pressure in a fluid at rest when the depth increases?

• It remains constant

• It decreases

• It increases

• It fluctuates
