Answer: Option (C) is the correct answer.
Explanation:
Biopower means production of electricity with the help of biomass. The unused wood, crops, agricultural residue, animal residue etc when burned then they help in generating biopower.
It is a renewable energy. Since biomass is readily available in most of the places. Therefore, the advantage of biopower is that it is also readily available in most places.
For example, bacterial decay produces a certain amount of heat which further helps in the production of energy.
Explanation:
The given data is as follows.
, 
= 2257 kJ/kg, 
= ?
For water, 
= 4.184 
Formula to calculate heat of vaporization is as follows.
= 
Hence, putting the values into the above formula as follows.
=
= 
= 2257 kJ/kg - 376.56 kJ/kg
= 1880.44 kJ/kg
Thus, we can conclude that enthalpy of liquid water at 
is 1880.44 kJ/kg.
Answer:
Coefficient
Explanation:
I am not that sure, but just wanted to help.
Answer:
A delta is formed when the river deposits its material faster than the sea can remove it. ... Cuspate - the land around the mouth of the river juts out arrow-like into the sea. The Ebro Delta. Bird's foot - the river splits on the way to the sea, each part of the river juts out into the sea, rather like a bird's foot.
