Decomposition: is the process by which organic material is broken down into simpler forms of matter. Therefore the energy in both is lessening/wearing away. The energy is less then it would be if it was up and running.

During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
What is happening to energy in sublimation?
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
What was happening in history during Gregor Mendel life span?
Yes, there were events happening all over the world.
How does thermal energy cause substances to undergo chemical change how does thermal energy cause substances to undergo chemical change?
Thermal energy cause thermal decomposition of a compound; the bonds between atoms are weakened.
What is a breakdown of substances into simpler molecules called?
Decomposition
Is energy absorbed or released during a decomposition reaction?
Energy is released during a decomposition reaction.
During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
Do decomposition reactions require energy?
False. It requires heat - Lowering the temperature ie. refrigeration slows decomposition - freezing say in liquid nitrogen will virtually halt decomposition completely.
What is happening to particle motion and thermalheat energy during melting?
Particle motion and thermal heat energy should both be increasing
What are the harmful effects of decomposition?
Methane gas is released, as well as carbon dioxide, during decomposition.
What does a substance break down into during a decomposition reaction?
A substance breaks down into two or more simpler substances during a decomposition reaction.
What is produced during decomposition?
Carbon Dioxide
Can you ever stop using energy?
No, you can never stop using energy. Even in death, energy is used for decomposition.
What occurs during the decomposition of iron ore?
hydrolysis
What occurs during a decomposition?
a compound partitions into its components
What is given out during decomposition?
That depends on what is being decomposed.
What gas is produced during decomposition of fruit?
ethylene
