What are the two processes underlying this image that turn peat into coal
2 answers:
Answer: Option (D)
Explanation: In order to form coal, two processes might be undergone and they are as follows-
- Peatification- It is the process by which the remains of trees and plants undergoes partial decomposition in a swampy type of environment, conserving organic matter. It is the first stage of coal formation.
- Coalification- It is the process of complete transformation of the dead remains of plants and trees into coal.
Thus the correct answer is option (D).

Here we have to choose the partial pressure exerted by the air in the given sample among the given options.
The partial pressure of the air in the sample is C. 96.82 kPa.
As per the Dalton's law of partial pressure the total pressure of the gas in the pool (P) is equivalent to the summation of the partial pressure of water vapor and air pressure.
Mathematically we may write:
Now the
Or, P_{Air}[/tex] = (100.18 - 3.36) kilopascals
Or, P_{Air}[/tex] = 96.82 Kilopascals.
Thus the partial pressure of the air in the sample is C. 96.82 kPa.
