# Fluids

```
Density(g/cm^3) = mass/volume
Volume(cm^3) = mass/density
Mass = Density(g/cm^3) * volume(cm^3)
Pressure = Force/Area = 1N/1M^2 = 1Pa
P(Pressure)V(Volume) = NRT(Temperature)
Speed = Wavelength x frequency
Frequency = waves/sec
1wave/1sec = 1Hertz
```
Solid has a volume, set shape, and can be compress.
Liquid has a volume, flow, but it's shape is it's container.
Gas volume and shape is it's container, it can flow and can be compress.

Difusion = high concentration to low conceentration.

Brownian motion = particles always moving (Not at absoulte zero)

Expanding and contracting = Materials expand when heated and contract when cooled.
Water doesn't contract when freezes

Density can be g/cm^3 or cc or mL

Solid -> Liquid = melting
Liquid -> Solid = freezing
Solid -> Gas = Sublimation
Gas -> Liquid = vaporize
Liquid -> Gas = condensation
Gas -> Solid = deposition

Presure is how hard and often gas molecules hit you, the more molecules hit you, the more presure you feel.

Pressure in a fluid depends on the weight of fluid above.

## Buoyancy

Buoyant force(or upthrust)

Displacement = pushes away/ take the place of

Drag is the resistance force that you experance when traveling through air.

Drag(Fluid Friction) can be affected by shape(streamlined) or speed.
