Question

State whether the following statements are true or false :
(a) The pressure exerted by a liquid depends on the area of base of its container.
(b) A drinking straw works on the pressure exerted by the liquid filled in a soft drink bottle in which it is placed.

Answer 1

Answer:

1. False because liquid pressure depends on height of air column not the area of base.
2. That's true.

Answer 2

(a) False ; (b) True

Explanation:

(a) The pressure exerted by a liquid depends on the area of base of its container -- False, the liquid pressure depends on the height of the column of air above it.

(b) A drinking straw works on the pressure exerted by the liquid filled in a soft drink bottle in which it is placed -- True.

Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it.
