Explanation:
This is because the fungi and bacteria are the decomposer, and their job is to decompose dead organism.
Answer:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
Explanation:
Answer:
positive
positive
Explanation:
Entropy -
In a system, the randomness is measured by the term entropy .
Randomness basically refers as a form of energy that can not be used for any work.
The change in entropy is given by amount heat per change in temperature.
- When solid is converted to gas entropy increases,
As the molecules in solid state are tightly packed and has more force of attraction between the molecules, but as it is converted to gas, the force of attraction between the molecule decreases and hence entropy increases.
So,
The particles of the substance , if are tightly held by strong force of attraction will decrease the entropy ,
And
If the particles are loosely held , the entropy will increase , i.e. , positive entropy .
Similar with solid converting to liquid , the entropy will increases , i.e. , positive entropy .
Hence ,
The correct sign of entropy for both the process is positive .
