uniformly spread out
the basic particle of matter from which all other matter is
constructed (building blocks of life)
materials made of two or more substances that can
separated by physical means
what is the smallest particle of a substance that can exist on its own
Heterogeneous mixture
atom
mixture
Homogeneous mixture
what is a solution
homogeneous mixture of particles so small that they
cannot even be seen with a microscope and will never
settle to the bottom of their container.
what are examples of solutions
Vinegar
Unopened soda
Hydrogen Peroxide
water
what is a colloid
atom
type of mixture with particles that are larger than
those in solution, but still too light to settle out.
homogeneous mixture of particles so small that they
cannot even be seen with a microscope and will never
settle to the bottom of their container.
heterogeneous mixture containing a liquid in which
visible particles settle.
what are examples of colloids
soda
Milk (Water & Fat),
Fog (Water & Air),
cool whip
what is a suspension
homogeneous mixture of particles so small that they
cannot even be seen with a microscope and will never
settle to the bottom of their container.
heterogeneous mixture containing a liquid in which
visible particles settle.
type of mixture with particles that are larger than
those in solution, but still too light to settle out.
atom
what is the Tendall effect
Detecting colloids is sometimes difficult so shining a beam of light at colloid will make the light scatter – this scattering of light by a colloid.
suspension examples
fog
Italian dressing,
Italian dressing,
chocolate milk
Definite Shape
Definite Volume
Particles closely packed in geometric arrangement
Indefinite Shape
Definite Volum
Particles have more space and slide pass each each other
Indefinite Shap
Indefinite Volume
Particles have energy to spread out evenly in container
High temperature gas
Particles are positively and negatively charged
Which Statements are true of the Kinetic Theory?
All matter is composed of particles
Particles are in constant, random motion
Particles collide with each other and walls of their
container
Particles stay in the same state and occupy their container
Kinetic Theory:
(a)
Matter is anything that has ________ and takes up __________
(a)
Kinetic Theory = (a) Theory
The state of a sample of matter depends on (a)
Temperature – related to the average (a) of an object; when the temperature increases (when heated)
objects (b) and objects (c) when cooled.
# Exception to Rule: (a) expands when cooled
