If politics is associated with religion it will not be in consonance with the provisions of the Constitution. It will be very harmful if a political party favours one religion and uses it to get more votes. It may lead to conflict between different groups of people based on religious ideology. Politics and religion do not and should not go hand in hand in a secular democratic state. A secular government refrains from associating itself with or serving the interests of any one religious community. It has to work for the welfare and betterment of the constituency, regardless of their religious inclinations.

The boiling point of the solution is 273.41 k
GIVEN
Weight of urea = 6 grams
weight of Glucose = 9 grams.
Weight of water = 300 grams
TO FIND
The boiling point of the solution.
SoOLUTION
We can simply solve the given problem as follows-
To calculate the boiling point of the solution, we will apply the following formula -
∆Tₒ = Kb× b × i (eq 1)
Where,
∆Tₒ = boiling point elevation
Kb = ebullioscopic constant of the solvent ( kb = o.515 kg/mol)
b = molality of the solute
i = van't Hoff factor of solute ( since urea and glucose are non-ionic compounds, so, i= 1)
We know that,
Boiling point elevation is defined as :
ΔTₒ = T₁ - T ........(eq2)
where,
T₁ = boiling point of the solution
T = boiling point of the solvent (T = 273.15 k of water)
Now,
{tex}\begin{aligned} & \text { number of moles of urea }=\frac{\text { given weight of urea }}{\text { molar mass of urea }} \\ & = \\ & \frac{6}{60}=0.1 \text { moles } \\ & \text { number of moles of glucose }=\frac{\text { given weight of glucose }}{\text { molar mass of glucose }} \\ & =\frac{9}{180}=0.05 \text { moles } \\ & \text { Total moles of solute }=0.1+0.05=0.15 \text { moles } \\ & \text { molality of solute }(b)=\frac{\text { moles of solute }}{\text { mass of solvent in } \mathrm{kg}} \\ & b=\frac{0.15 \times 1000}{300} \\ & b=0.5 \mathrm{M} \end{aligned}{/tex}
putting the values in ( eq 1) we have
ΔTₒ = 0.512 × 0.5 × 1
ΔTₒ = 0.26 k
Now, putting the value of ΔTₒ in (eq 2)
ΔTₒ = T₁ - T
0.26 = T₁ - 273.15
T₁ = 273.15 + 0.26
T₁ = 273.41 k
Hence, The boiling point of the solution is 273.41 k
