جب خالص پانی میں نمک ملایا جائے تو اس کا ابلتا نقطہ؟
A. None of the above
B. Decreases
C. Remains same
D. Increases
Explanation
When salt is added to pure water, the boiling point of the solution increases. This is known as boiling-point elevation.
The boiling point of a solution is higher than that of the pure solvent (water) because the dissolved salt particles disrupt the formation of vapor bubbles, requiring more energy to overcome the surface tension and escape the solution as vapor.
