100
A type of change where a NEW substance is formed. The new substance has different properties from those of the reactants.
What is a chemical change?
100
An example is sugar dissolved in a solution.
What is the solute?
100
The two was that liquid can become a gas.
What are evaporation and boiling?
100
The formula for calculating density.
What is d=m/v
100
The is the method used to remove iron filings from a mixture.
What is magnetism?
200
Color, shape, and solubility are examples.
What are physical properties?
200
This is water's role in a solution.
What is a solvent?
200
This is what happens to particles when you increase the temperature in a gas.
What are faster movements and more spreading?
200
The density of water.
What is 1g/mL or 1g/cm3
200
This method is used to recover dissolved salt from a solution.
What is vaporization? (boiling or evaporation)
300
Combustion, oxidation and electrolysis are examples of this type of change.
What is a chemical change?
300
A substance that cannot be broken down into simpler substances.
What is an element?
300
This is a description of particles in a solid.
What is vibrating in one position?
300
This is the density when the mass is 30g and the volume is 10mL.
What is 3g/mL?
300
The method you would use to separate sand from water.
What is filtration?
400
This law states that matter is not created or destroyed.
What is the Law of Conservation of Mass?
400
A mixture in which the different substances are visible.
What is a heterogeneous mixture?
400
According to Boyle's Law, if the temperature and mass are constant, this is what will happen when you decrease volume.
What is an increase in pressure?
400
This is a method to measure the volume of an irregular shaped solid.
What is the displacement of water?
400
The two steps of distillation.
What is evaporation followed by condensation?
500
This type of reaction releases thermal energy.
What is an exothermic reaction?
500
This type of homogeneous mixture does not let light pass through.
What is a colloid?
500
This law states that at a constant pressure, when temperature increases, volume will increase.
What is Charles's Law?
500
This is how you know if a substance will sink or float.
What is a density or greater or less than 1g/cm3?
500
The method used to separate different colors in ink.
