Particle Theory Of Matter
Particle theory of matter ISTAMP 1. All matter is made up of particles. 2. All particles are in constant motion 3. All particles of one substance are identical 4. Temperature affects the speed at which particles move. 5. In liquids and solids, the particels are close together and have strong forces of attraction between them 6. In a gas, there are spaces between the particles.
Viscosity
Affects of Temprature
Buoyancy
Pressure
Density
Viscosity is a measure of a fluid's resistance to flow.
When temperature increases the fluids viscosity goes down making the fluid flow easily.

If the density of the object is greater than the fluid it is in it will sink
If the density is lower it will float
If the density is the same it will hover

For solid its Grams per cubic centimeters
For gasses its kilograms per liter
You calculate density by doing mass divided by volume
Buoyancy is the tendency of a object in a fluid to rise or sink due to its density differences with its surroundings.
When a solid body is partially are completely immersed in a fluid, the fluid exerts an upward force on the body, whose magnitude is equal to the weight of the displaced fluid.

Air pressure changes with altitude
Pressure in a fluid changes with its depth
Pressure is the amount of force applied to a given area
Compression is a decrease in volume caused by force
Pressure is force divided by area
f= mass (kg) x 10 newtons per kilogram
Weight x 10
