Formation of manure from leaves is a physical change?
Farmyard manure creates heat energy from decomposition of leaves. There is also physical change because the leaves' structure is broken down. The main factors for producing good manure are: water, which is already part of the manure; heat, which is generated by the decomposing leaves; and air, which is needed to aid the decomposition, because decomposition is a very slow form of "burning". Quite a high temperature can be generated in a manure heap or a compost heap.
Why is heat not a matter?
Heat does not occupie space, and does not have definite volume, so it is not a matter!!!!^_^
What pure substance can be broken down by heat?
Carbon into carbon monoxide and carbon dioxide
Why do gardeners add water to their compost heap from time to time?
To cause the material to heat up and aid decomposition.
What is thermal decomposition?
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
Why does the snow on your compost pile melt faster than the snow on the ground?
The accelerated melting of snow on compost as opposed to the ground, is the heat produced in the decomposition of organic matter.
Why is decaying matter warm?
The chemical processes involved in decomposition generate heat.
Is petroleum a compound?
No, a mixture.
Why is decomposition of vegetable matter considered exothermic?
This is exothermic because the pile releases heat as the microbes in the pile release energy as heat when they compost the matter. -Super Llama
Why does garden mulch have a bad odor?
Garden mulch is decomposing as organic matter does. The odor is caused by bacteria breaking it down. The decomposition produces heat which is why it's warm when in large piles and will emit steam at early morning.
What is the effect of heat on decomposition?
Heat speeds up the decomposition process
Is decomposing a chemical or physical ch ange?
Both, usually. Consider a compost heap in the back garden - this is decomposing plant matter. The decomposition is chemical as compounds break down into smaller, simpler organic molecules and heat is given off (exothermic). Decomposition is also physical as some of the simpler molecules produced by decomposition includes liquids and gases so a solid decomposes into solids, liquids and gases.
Why does horse manure get hot?
because it bakes in the sun all day The decomposition of the vegetable matter in the dung creates heat.
Write a word equation to describe the decomposition of copper on heating?
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
Write a word equation to describe the decomposition of copper carbonate on heating?
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
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.
How will soil with high orgnaic matter effect soil temperature?
When bacteria are breaking down organic matter they are giving off heat.
