It's Elementary, My Dear Watson
100
The stuff that makes up everything in the universe.
What is matter?
100
I have definite volume, but no definite shape.
What is a liquid?
100
This law states that if volume stays the same and temperature increases, so does pressure.
What is Gay-Lussac's Law?
100
This law states that the total amount of energy stays the same in any physical or chemical change.
What is the law of conservation of energy?
100
How the elements in the periodic table are arranged and what their number refers to.
What is the atomic number, the number of protons in the nucleus of an atom?
200
These are the two types of matter.
What are mixtures and pure substances?
200
I have definite shape and definite volume.
What is a solid?
200
According to this law, when the pressure of a gas increases, its volume decreases.
What is Boyle's Law?
200
These are the two types of vaporization.
What are boiling and evaporation?
200
The type of electrons found in the outer shell of an atom.
What are valence electrons?
300
Matter changes whenever this is added or taken away.
What is energy?
300
I have no definite shape and no definite volume. I will expand to fill any container.
What is a gas?
300
This law states that when the temperature of a gas increases, its volume increases.
What is Charles' Law?
300
How a solid turns into a gas. For example, when dry ice turns into a gas.
What is sublimation?
300
These are the most reactive metals. For example, sodium.
What are the alkali metals?
400
The difference between a physical and chemical change.
What is that chemical changes result in the formation of a new substance?
400
I'm a solid whose particles form no specific pattern, like plastic, rubber or glass.
What is an amorphous solid?
400
A measure of the average energy of motion of the particles of a substance.
What is temperature?
400
How a gas turns into a liquid. For example, when steam turns into water.
What is condensation?
400
The reason elements in the same group have similar properties.
What is that they share the same number and arrangement of valence electrons?
500
Properties that hold true for a particular substance no matter what. For example, the boiling point of water or the hardness of a diamond.
What are characteristic properties?
500
I'm a solid whose particles have a regular, repeating pattern, like salt, sugar or sand.
What is a crystalline solid?
500
True or false, molecules of gases have the least amount of energy.
What is false?
500
The two types of energy we studied and their definitions.
What are thermal and chemical energies? Thermal: The total energy due to movement/vibration Chemical: Energy that comes from chemical bonds
500
The class of elements that best conducts electricity.
What are metals?
