A state of matter in which the substance takes the shape of its container. It has high kinetic energy.
What is gas?
100
The smallest part of an element that can exist and still retain the characteristics of that element.
What is an atom?
100
The substance that is dissolved in a solution.
What is a solute?
100
To change from a liquid to a gaseous state. Water does this when you heat it to 100 Degrees Celsius.
What is to boil?
100
An element or compound that enters into chemical reaction.
What is a reactant?
200
A state of matter in which the substance has definite volume but takes the shape of its container. It has medium kinetic energy.
What is liquid?
200
A pure substance in which all the atoms are the same
What is an element?
200
A mixture in which very small particles of a solid remain undissolved.
What is a suspension?
200
To pour off the top layer without disturbing the layers or the sediment below.
What is decanting?
200
A substance obtained from one or more other substances as a result of a chemical reaction.
What is a product?
300
A state of matter in which the substance has definite shape and volume. It has low kinetic energy.
What is a solid?
300
The smallest part of a compound that can exist and still retain the properties of that compound.
What is a molecule?
300
A homogenous mixture in which the solute is uniformly distributed throughout the solvent.
What is a solution?
300
The process of vaporizing and then condensing a liquid.
What is distillation?
300
The force of attraction between the particles/molecules of a substance (think of the 'arms linking' between molecules).
What is cohesion?
400
A change in substances that have reacted chemically. The original substance is changed to a new substance and cannot easily be recovered.
What is Chemical Change?
400
A pure substance containing two or more elements united chemically. The molecules are all the same.
What is a compound?
400
The substance that does the dissolving in a solution.
What is a solvent?
400
The amount of mass in a substance.
What is density?
400
All of the atoms or molecules of the substance are the same. Gold is an example of this.
What is a pure substance?
500
A change in a substance where no new substances are formed, although the substance itself takes on different characteristics. It is a reversible change.
What is Physical Change?
500
The force of attraction between the surface of unlike bodies such as a solid and a liquid.
What is adhesion?
500
Referring to a solution that is not able to hold anymore solute at that temperature.
What is saturated?
500
The process of passing a mixture of a liquid and a solid slowly through paper or other porous substance in order to remove the solid from the mixture.
What is filtering?
500
A mixture of varying composition. e.g. a mixture of soil and sand may have more of one component in one sample than in another sample of the same size taken elsewhere from the mixture.
