Since you didn't have any extra information about the question I'll be presenting an example from my own textbooks that I've used.
An example of a direct observation is listening to a cricket chirp at night, and counting the number of chirps per minute.
Direct Observation is where the evaulator watches the subject in their usual habitat without disrupting or altering it.
Answer: Yes I-P-Cl = 90
Explanation:
This is because the angle formed between I-P-Cl is perpendicular hence the angle is 90°
Answer:

Explanation:
Answer:
Option (A)
Explanation:
The dew point refers to the temperature at which the amount of water vapor present in the air is so high that the relative humidity becomes 100%, and with the increasing rate of cooling, the condensation process takes place and dew is formed.
So for dew point to occur, the air temperature must reach a condition where the air is fully saturated or the relative humidity is 100%.
Thus, the correct answer is option (A).
0.24J/g*degC * 4.37g * 2.5degC = 2.622J
The 2.5 degC is the difference between 25 and 27.5 deg C.
