Energy Types
Energy from movement of particles.
What is Thermal Energy?
Energy being moved from one place to another without changing forms.
What is an Energy Transfer?
During a physical change a new substance is created. True or False
False
3 signs of a chemical change.
2. Bubbling (gas production)
3. Precipitate
4.Heat or Light
5. Temperature or mass change
Number of Nitrogen atoms on Reactant side?
4NH3 + 4O2 = 4NO + 6H2O
What is 4
Energy stored in the bonds of a molecule.
What is chemical energy?
Energy being changed from one form to another.
What is energy transformation?
The phase change from gas to solid
What is deposition?
Breaking a chemical bond to form 2 or more atoms.
What is a decomposition reaction?
Number of Oxygen atoms on Product side?
4NH3 + 4O2 = 4NO + 6H2O
10
Energy stored in a moving object with a certain mass and position.
What is mechanical energy?
The energy transformation that occurs in a light bulb.
What is electrical to radiant + thermal?
The physical change that occurs when salt and water are mixed together.
What is dissolution?
Mixing 2 solutions to create a solution and an insoluble solid
What is a precipitation reaction?
Number of Hydrogen atoms on Reactant side?
4NH3 + 4O2 = 4NO + 6H2O
12
Energy stored and moved by electromagnetic waves.
What is Radiation/Radiant Energy?
The energy transformation that occurs when you go for a run.
What is Chemical to Mechanical + Thermal?
The physical change that occurs when something changes shape.
What is a deformation?
2 or more Atoms form a chemical bond to create a new molecule.
What is a synthesis reaction?
Does this chemical equation follow the law of conservation of matter? Why?
4NH3 + 4O2 = 4NO + 6H2O
No
More oxygens on products side than reactants
The average speed of the particles in a substance. A component of Thermal Energy.
What is Temperature?
The path of energy from a hydroelectric dam to a toaster.
Hydraulic (Mechanical) to electrical.
Transfer of electrical through power lines.
Electrical to Thermal
Another word for the melting phase change.
What is fusion?
This type of reaction: 4Fe + 3O2 = 2Fe2O3
What is an oxidation reaction?
Does this chemical equation follow the law of conservation of matter? Why?
2KClO3 = 2KCl +3O2
Yes
Same atoms on either side
