MCQ
A beaker containing a liquid is kept inside a big closed jar. If the air inside the jar is continuously pumped out the pressure in the liquid near the bottom of the liquid will:
  • A
    Increase
  • ✓
    Decrease
  • C
    Remain constant
  • D
    First decrease and then increase.
✓

Answer

Correct option: B.
Decrease
As the air inside the jar is pumped out, the air pressure decreases. Thus, the pressure in the liquid near the bottom of the beaker decreases.
