PASCAL'S LAW
Pascal's law states that when force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid. An important breakthrough in our understanding of fluids occurred in mid - 1600s.

RULES OF PRESSURE

Pressure: Pressure is the amount of force applied to a given area. Air exerts pressure around you at all time like what water does when you swim underwater. Air pressure is the reason your ears may pop sometimes when you change altitude quickly. Due to the altitude change your ears have to adjust to the pressure of the new altitude resulting in a popping sound being heard by you.
Changes in Pressure: Air pressure changes with altitude. The layers in Earth's atmosphere extend mode than 160km above Earth's surface.
Pressure and Depth: Pressure in fluid also changes with its depth. Ex. The weight of water in the upper part of a swimming pool presses down on the water in the lower part of the pool.
Pressure and Fluid Flow: If a fluid is allowed to move, it will always go from an area of higher pressure to an area of lower pressure. You make use of this property when you use a straw to drink from a juice box.
Pressure and Temperature: When the pressure inside a container has it's temperature of a fluid increased the pressure exerted by a fluid is the sum of all the forces exerted by the individual particles in fluid.

ARCHMIDES PRINCIPLE
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
