-
What are the four states of matter?
-
What is density?
Density is how close the atoms are; the mass per volume.
-
What is compressibility?
Compressibility is the ability to squish matter into a smaller space.
-
What is diffusion?
Diffusion is the ability to of the atoms to move away from other atoms.
-
What is the solid's volume, shape, density, compressibility and diffusion?
- definite VOLUME
- definite SHAPE
- high DENSITY
- low COMPRESSIBILITY
- low to none DIFFUSION
-
What is the liquid's volume, shape, density, compressibility and diffusion?
- definite VOLUME
- no definite SHAPE
- medium DENSITY
- slight COMPRESSIBILITY
- medium DIFFUSION
-
What is the gas' volume, shape, density, compressibility and diffusion?
- no definite VOLUME
- no definite SHAPE
- low DENSITY
- high COMPRESSIBILITY
- high DIFFUSION
-
what is plasma?
- - It's considered to be the fourth state of matter
- - most abundant state in the universe, less abundant in Earth
- - Ionized gases, extremes of gas properties and positive ions
-
Rank solid, liquid, gas and plasma from the strongest to weaker IMFs.
-
What are molecules, atoms and ions?
- molecules - tow or more atoms stuck together
- atoms - smallest unit of life
- ions - charged atoms
-
What explains/describes the movement of molecules, atoms and ions?
KMT or kinetic molecular theory
-
FILL IN THE BLANK:
KMT explains the behaviour of _______ the best because it has ________ IMFs. It does not explain the behviour of _______ and ______ very well.
- gas
- little to no
- solid
- liquid
-
What is the kinetic molecular theory?
(4 points)
- - All matter is made up of small particles
- - These particles are in constant random, straight line motion. It bounce off each other and the container wall molecules.
- - The bouncing collisions between particles are perfectly elastic.
- - The kinetic energy of particle determine the speed or movement of that particle. We measure K.E. using temperature.
-
What are the two types of solid?
- Amphorous solids
- Crystalline solids
-
What are the four types of crystalline solids?
- Covalent- network
- Ionic
- Molecular
- Metallic
-
What is an amphorous solid?
a type of solid that don't have any pattern or arrangement.
-
What is a crystalline solid?
It has a distinct repeating pattern of particles.
-
What makes up a covalent-network?
one type of non-metal atom
-
What makes up an ionic bond?
non-metal and metal
-
what makes up a molecular solid?
2 or more non metals
-
What makes up a metalic solid?
metals
-
From strongest to weakest, rank the types of crystalline solids.
- Metallic solid
- Covalent/Ionic
- Molecular
