Heat is a relative term. Hot, as in cooking or a very warm day, or room temperature. Freezing can be 32 to -32.
Decomposition usually describes something being eaten by microbes that turn the large molecules into smaller ones, producing smelly waste gas, and such. Turning something into a pile of goo.
The warmer it is, the quicker most bacteria can do their job. Room temperature has heat, not necessarily added heat. In a home freezer the bug will work slower, but some can still live and eat in.

What kind of reaction is Copper II hydroxide plus heat?
Decomposition!
How can you determine if the decomposition of potassium chlorate is complete?
Decomposition of potassium chlorate is heat melting, so when you see that the powdered potassium turned into liquid, then it's done.
What is the thermal decomposition of sodium carbonate?
The thermal decomposition of sodium carbonate is a chemical reaction according to the equation: Na2CO3 -> Na2O + CO2. The reaction is endothermic and therefore proceeds rapidly in the direction shown only in an environment from which ample heat energy can be absorbed.
Equation of decomposition of copper nitrate?
2Cu(NO3)2(s)+heat------->2CuO(s)+4NO2(g)+O2(g)
Write a word equation to describe the decomposition of copper on heating?
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
What is the effect of heat on decomposition?
Heat speeds up the decomposition process
Does heat help decomposition?
yes
What kind of symbol is used to show that heat is needed in decomposition reaction?
There is no symbol that will show weather or not heat is needed in a decomposition reaction.
If you break a compound down by using heat it is called?
Solids melt on heating. A2. But if you are thinking of the destruction of the material, perhaps pyrolysis is what you seek.
Thermal decomposition and decomposition temperature-is it refer to the same things?
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.
How does presence of light affect the rate of decomposition?
light will produces heat which will speed up the rate of decomposition.
What are some examples of a decomposition?
I think of decomposition as organic processes. For example wood rotting (or anything else rotting). However, decomposition can also be a chemical process. For example, if you heat wood chips sufficiently without fire, or without inadequate oxygen, they will decompose into a mixture of light gasses often termed as wood gas.
What does the decomposition of organic matter by heat describe?
Pyrolysis
How do you cook fish without heat and the process of marinating?
It's not possible to cook it without heat or marinating, but it can be eaten raw as sushi.
What is non loss decomposition?
Nonloss-decomposition is data normalization without the loss of information.
How can you have temperature without heat?
only one possible reservation: the case of "absolute zero" where there is no heat to be found
What is it called when heat breaks up a substance?
Thermal Decomposition
