Options
- ATo increase the boiling point of the liquid
- BTo decrease the boiling point of the liquid
- CTo keep the pressure constant
- DTo cool the liquid
Correct answer
B. To decrease the boiling point of the liquid
Step-by-step solution
A water pump or vacuum pump is used in distillation under reduced pressure to decrease the boiling point of the liquid by reducing the pressure on its surface.
