Pressure: is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
smaller the area is the mor pressure is gater 🔪
One nail: it brakes skin
A bed of nails:skin dosen't break :bed:
pressure distribuates
pressure under water:droplet::
more pressure
greater the depth: higher the ptessure
the water weight is
above you
pressure all around you not
only in one place
air pressure: it variates
pressing down to earth is atmospheric pressure
so bars equal pressore
weather fronts: cold and hot air meet :tornado:
Viscosity and density
Brownian Motion
Anything that takes up space and mass is called 'matter
All matter is made from particles.

3 states of matter
Anything that takes up space and mass is called 'matter
All matter is made from particles.
higher temerature particles move faster
intermolecular fores hold particles
solids can
flow over each other
be malleable or brittle
strong
waxy
hard
soluble
conduction
vischious: the intermolecular force is not enough stong.
Alloys: mixtures of metals
browain moton: movement of particles
kinethic teory: matter made of particles
comprehended by Einsein
water can' colpress
When the intermolecular forces between particles of the gas and the water particles are stronger than those between then the gas will dissolve I the water.
It is the same for liquid.
waves
longitudinal: back and forth
traverse: go up and down
superposition: waves combine
Superposition produces bigger waves.
If the crest coincides with the
trough it would disappear
Waves in water and light waves are transversal waves- They osliclcate up and down forming crests and troughs
the numbers of waves per second: frequency HERTS
OPAQUE: the material that blocks the passing of light
Materials that light waves can pass through freely are said TRANSPARENT
TRANSLUCENT: materials that allows only some light to pass
Opaque and Translucent material absorb light
The reflection produced by a flat, smooth surface is called SPECULAR REFLECTION
MEDIUM = IS WHERE WAVES TRAVEL TROUGH
