Answer:
Relative humidity is low . 
Explanation:
The wet bulb reads low temperature because due to low humidity of atmosphere , evaporation of water takes place from the wet bulb which makes the bulb cool and therefore it reads lower temperature . In the process of evaporation , heat equal to latent heat of vaporization is taken from the bulb and it loses temperature. 
 
        
             
        
        
        
Answer: Option (3) is the correct answer.
Explanation:
When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.
Atomic number of chlorine is 17. So, number of electrons present in  is 17 + 1 = 18 electrons.
 is 17 + 1 = 18 electrons.
Atomic number of cobalt is 27. So, number of electrons present in  is 27 - 4 = 23 electrons.
 is 27 - 4 = 23 electrons.
Atomic number of iron is 26. So, number of electrons present in  is 26 - 2 = 24 electrons.
 is 26 - 2 = 24 electrons.
Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.
Atomic number of scandium is 21. So, number of electrons present in  is 21 + 2 = 23 electrons.
 is 21 + 2 = 23 electrons.
Thus, we can conclude that out of the given species,  has the greatest  number of electrons.
 has the greatest  number of electrons.

Answer:
R is universal gas constant
It is has fixed value which would depend upon the units in which P,V and T expressed in the equation PV=nRT
R= 
nT
