gas
Moves randomly, particles don't touch and stay in the shape of its container
liquid
Moves randomly but still touches sometimes, stays in the shape of its container
solid
stays in a fixed position, vibrates in the same position, are touching, does not stay in the shape of its container
solid, liquid, gas
Sort the three states of matter into order of increasing energy
gas, liquid, solid
Sort the three states of matter into order of decreasing energy
physical changes
What term can be used to describe interconversions between states of matter?
melting
What is the name for the physical change when a solid turns into a liquid?
freezing
What is the name for the physical change when a liquid turns into a solid?
boiling / evaporating
What is the name for the physical change when a liquid turns into a gas?
condensing
What is the name for the physical change when a gas turns into a liquid?
something that is made up of only one element or compound
What is a pure substance?
What is a mixture?
when there are two or more elements or compounds not chemically bonded
What process is this a diagram of?
filtration
Give the term being defined: The temperature at which a liquid boils.
boiling point
Give the term being defined: A specific temperature at which a solid turn into a liquid.
melting point
Give the term being defined: Solution passing through a filter.
filtrate
Give the term being defined: Describes a substance that cannot be dissolved in a certain liquid.
insoluble
Give the term being defined: Contains the maximum amount of solute that can dissolve in that amount of solvent at that temperature.
saturated solution
Give the term being defined: Substance that dissolves in a liquid to make a solution.
solute
Give the term being defined: Formed when a substance has dissolved in a liquid.
solution
Give the term being defined: The liquid in which a solute dissolves to make a solution.
solvent
Which state of matter takes a fixed position?
solids
Will substances expand when they are hotter or colder?
hotter
True or False: substances contract when they are colder
True
Saturated Solution
a mixture cannot dissolve any more solute because they do not have enough spaces between the particles
Pure substances
something that only contains one type of particle (can be chemically joined)
A mixture/ impure substance
2 or more substances that are mixed together but are not chemically joined.
Solution
A mixture that is made when a solid dissolves and mixes with a liquid
Filtering
Method used to separate an insoluble solid from a liquid
Insoluble
Something that is unable of dissolving
Soluble
Something that can be dissolved
Evaporation
Method used to separate a soluble solid from a liquid, also known as the process of turning a liquid to a gas
Dissolve
A solid that incorporates into a liquid to form a solution
Solute
A solid that dissolves
Solvent
A liquid that does the dissolving
Diffusion
movement of particles that allows them to spread out and mix with other particles, when particles move from an area of high concentration to an area of low concentration.
How does the kinetic energy of the particles increase?
it rises along with the temperature
All particles are attracted to each other: explain in depth
Some particles are attracted to each other strongly, but others attract to each other weakly
True or False: Not all substances are made of particles
False
