Changes of State
What is it called when you go from a liquid to a solid?
freezing
What is a pure substance?
contains only one kind of particle throughout
Example: diamonds
The particles of matter are in constant motion
True or false?
True
What is a diluted solution?
A diluted solution is a solution with a low concentration of solute. (watered down)
Separating substances on the basis of appearance which may involve colour, size, texture, or composition.
Sorting
What is it called when you go from a liquid to a gas?
evaporation
What is a mixture?
Something that contains 2 or more pure substances.
Example: bread
Temperature does not effect the speed at which particles move
True or false?
False
What is a concentrated solution?
A concentrated solution is a solution with a high amount of solute.
Applying heat to the liquid to separate it from the solute particles.
Evaporation
What is it called when you go from a gas to a liquid?
condensation
What is a solution?
It is a mixture that looks the same throughout
Example: Milk
What is kinetic energy?
The energy of movement
What does it mean if something is insoluble?
It means it is unable to be dissolved
Example: olive oil and salt
Liquid evaporates to separate from solid and then cools in a separate container to turn back into a liquid.
What is it called when you go from a gas to a solid?
deposition
What is a mechanical mixture?
It is a mixture that looks the same throughout
Example: pizza
What is heat?
Heat is the energy that transfers from a substance at a higher temperature to one at a lower temperature
What is an unsaturated solution?
a solution that can take in more solute (can take more koolaid)
Separating iron, steel, nickel and some other compounds from the non valuable materials
Magnetism
What is it called when you go from a solid to a gas?
sublimation
What is matter?
Matter is anything that has mass and takes up space
What is temperature?
Temperature is the measure of the average kinetic energy(movement) of the particles in a substance
What is a super saturated solution?
A super saturated solution is when there is more solute than solvent (too much kool-aid then water so the kool-aid particles sit at the bottom)
Separating solids by component size.
sifting
