These are the two subatomic particles found in the nucleus of an atom.
What are proton and neutron?
100
Rusting, tarnishing, and reacting with other compounds are all examples of this.
What are chemical changes?
100
This is the science term for "stored energy."
What is potential energy?
200
This is what all matter is made of.
What are atoms?
200
This is defined as the average kinetic energy of the molecules or atoms.
What is temperature?
200
This can be physically separated because each individual component keeps its physical properties.
What is a mixture?
200
Ability to dissolve in water and density are examples of this type of property.
What is a physical property?
200
Kinetic energy is the energy of this.
What is motion or movement?
300
What is the meaning of the metric prefix kilo-?
What is 1,000?
300
This is what happens to kinetic energy of water molecules in a gas when it condenses.
What is they slow down?
300
This is the difference between an element and a compound.
What is elements are made of all the same kind of atom, while compounds are made of more than one type of atom?
300
This law discusses how the number of atoms on the reactant side of the equation should equal the number of atoms on the product side.
What is the law of conservation of mass?
300
This type of energy production directly contributes to climate change or global warming.
What is a coal-fired power plant?
400
This is the order (smallest to largest) of the following metric prefixes: kilogram, centigram, decagram, gram
What is centigram, gram, decagram, kilogram?
400
This is why objects feel cold.
What is because they remove heat from your hand? (Heat is the transfer of thermal energy--from an object of higher temperature to an object of lower temperature)
400
This is the atomic number for potassium, K.
What is 19?
400
This is the big number that goes in front of elements or compounds in a chemical reaction.
What is a coefficient?
400
An object has 500 J of kinetic energy when it leaves the ground. This is the maximum amount of potential energy it can have at its highest point. (There is no friction).
What is 500 J?
500
This is 4,502 kilometers converted into decameters. Use the conversions 1 km=1,000 m and 1 dam=10 m. Make sure your answer has units!

Draw and label a phase change diagram with the words: solid, liquid, gas, melting, and evaporating.
Solid, liquid, and gas are on the three slanted lines. Melting is on the flat line between solid and liquid. Evaporating is on the flat line between liquid and gas.
500
This is the atomic mass of helium, He.
What is 4.002 amu?
