Heat speeds up the decomposition process
yes
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
Solids melt on heating. A2. But if you are thinking of the destruction of the material, perhaps pyrolysis is what you seek.
in English it is basically breaking something down using heat --------------- Thermal decomposition is a chemical reaction of decomposition under the effect of high temperature: the compound breaks down into other substances when it is heated. For example: copper(II) sulfide when heated produces copper + sulfur dioxide
Extreme heat and cold will effect compost formation. Many times I have measured very active compost piles, with sufficient moisture, at 120 degrees F. Temperatures above may begin to adversely effect decomposition, depending on moisture present. I do not know at what higher temperatures decomposition slows or stops. Cold temperatures slow the metabolism of decomposition organisms. Therefore compost formation eventually stops at temperatures approaching freezing. The decay organisms vary greatly and their heat/cold tolerances will vary also.
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
light will produces heat which will speed up the rate of decomposition.
Pyrolysis
Thermal Decomposition
Moisture and warm temperature speed decomposition. This is a form of abiotic decomposition as it employs a chemical or physical process without the involvement of micro-organisms.
