What is a fluid? A substance that has the capacity to flow and assume the form of the container into which it has been poured.

What are some examples of fluids? Water, milk, blood and saliva Gases are also considered fluids: air, helium and ozone.

The Particle Model. Used to explain how fluids change shape. Arrangement Of Molecules In The Three States Of Matter – YouTube Solids, Liquids and Gases - YouTube

Odd Fluids Is toothpaste considered a fluid? What about sand?

There are two types of fluids: 1) Compressible fluids: A fluid whose volume can change. GASES. 2) Incompressible fluids: A fluid whose volume cannot be varied. LIQUIDS. Why are they different? Because the particles behave differently under pressure.

Pressure The result of a FORCE applied in a PERPENDICULAR fashion to a surface.

What is a force? A force is either a PUSH or PULL that changes the movement or shape of an object. Effect of force on pressure: Force increases = Pressure increases Force decreases = Pressure decreases

Surface area and Pressure If surface area increases = Pressure decreases If surface area decreases = Pressure increases

How to we calculate pressure? Pressure is equal to the force divided by the area. Pressure is measured in Pascals (Pa) Force is measured in Newtons (N) Area is measured in square meters (m²) 𝑃= 𝐹 𝐴

Pressure and Fluids, Part 2. Pressure exerted by fluids: When the fluid is incompressible, the force exerted comes from the mass of the fluid above the object.

How density affects pressure. Density is a measure of much matter is “packed together” in a solid/liguid/gas. The GREATER the density, the GREATER the pressure. SUMMARY: The pressure exerted on an object by an incompressible fluid depends on – The DEPTH of the object in the fluid. 2. The DENSITY of the fluid.

Liquid Pressure - YouTube

Pressure exerted by a compressible fluid The PRESSURE depends on: The number of particle collisions, with each other or with the sides of the container. Factors that affect the number of collisions: Number of particles Temperature – higher temperature, more collisions Volume of fluid

Gas volume and pressure - YouTube

Pressure and the volume of a compressible fluid. Volume increases – Pressure decreases Volume decreases – Pressure increases Pressure-Volume Relation ( Kinetic Molecular Theory ) - YouTube

Atmospheric Pressure The atmosphere is the layer of air that surrounds the earth. This air is a mixture of gases, and it exerts pressure on everything on the surface. We measure atmospheric pressure by using a barometer. QUESTION: What happens to a barometer the higher one goes in the atmosphere?
