Where in a substance is chemical energy stored?
chemical bonds
When a pure substance is heated or cooled but does not change state the energy as heat is the what?
chemical change
Is condesing a chemical change?
No, condensing is a physical change, not a chemical change. It is the process of changing a substance from a gas state to a liquid state by removing heat energy.
What are the differences between a chemical and physical change?
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
Is photosynthesis in leaves a chemical or physical change?
Photosynthesis is a chemical reaction. Using Sunlight, water, and carbon dioxide, plants can produce high energy sugars and oxygen. Here is the formula:Sunlight + 6H2O + 6CO2 ----> C6H12O6, 6O2
WHAT IS THE SUBSTANCE THAT PROVIDES ENERGY OF A chemical CHANGE?
catalyst
Substance that provides energy as the result of a chemical change?
Fuel. :)
A substance that provides energy as a result of a chemical change is a?
Fuels
What does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
What are the three energy conversions that might occur in a power plant?
I think is a fuel in a substance that provides to form of energy such as heat, light, electricity, or motion as the result of a chemical change.

A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
How do energy and changes in energy change the state of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
