Name four energy sources.
What is wind, solar, sound, mechanical, chemical, electrical, light, nuclear, hydropower, kinetic, potential
100
Describe the movement of molecules in a solid.
What is they are packed tightly and cannot move around.
100
State the Law of Conservation of mass.
What is mass cannot be created or destroyed it is just changed.
200
This chemical compound is written as two hydrogen and one oxygen.
What is water?
200
The elements on the left side of a chemical equation are known as this.
What is reactants?
200
State the Law of Conservation of Energy.
What is energy cannot be created or destroyed its just changed or altered.
200
Describe the movement of molecules in a liquid.
What is they are allowed to move around with space between them?
200
An exothermic reaction can be described as this.
What is energy (thermal) being released during a chemical reaction?
300
This is the total number of electron(s) Lithium has in the outermost level.
What is one?
300
Name the four clues to a chemical reaction.
What is gas formation, energy change, color change, and solid formation?
300
How does the Law of Conservation of Energy apply to the WATER CYCLE?
Energy cannot be created or destroyed just transferred over again as the Water Cycle uses water over but it changes form yet it is a continuous cycle.
300
Describe the movement of gas molecules.
What is they move around freely with space between them?
300

An atom can become a positive ion by doing this.
What is losing electrons?
500
Explain the term viscosity.
What is the thickness of a fluid. How much fluidity depends on how thick the substance is.
500
When a cake is baked, why is the mass of the batter different from the mass of the cake.
What is energy is absorbed (endothermic) and changes the mass to weigh less.
