Hi Rachana,
When glucose is added to water it increases the boiling point of water. This is because the pressure of the system does not depend on the pressure of the glucose or the solute present. To make the vapour pressure equal to atmospheric pressure we heat this solution a little bit and due to which the boiling point increases of the solution. We know that according to boiling point elevation T=i (Kb) m . This shows that concentration of the solute is directly proportional to the Boiling point.
Here T is change in temperature.
i is Van't Hoff factor
m is molality of the solute
Kb is molality boiling point constant
I hope you got your answer.
