Question

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

Answer 1

Hint: Force is defined as the push or pull experienced by the object because of another object. If we connect pressure with force then we can observe that, a particle is pushed from high pressure towards lower pressure.

Complete step by step answer:The relation between force and pressure is that a particle gets pushed from higher pressure to the lower pressure. This concept works in case of straw in a soft drink bottle because, when you suck the air out of the straw it creates a decreases in the air pressure inside of the straw since the atmospheric pressure is greater on the outside of the straw compared to the inside of the straw, the liquid is forced out inside the straw.
The liquid at the bottom of the liquid bottle has higher pressure and the pressure on the liquid increases with depth. Therefore, the liquid is pushed form the higher pressure to the lower pressure.
This is how the liquid is pulled inside the straw.
Thus the statement, ‘A drinking straw works on the pressure exerted by the liquid filled in a soft drink bottle in which it is placed’ is true.
Therefore, from the above explanation, the correct answer is, option (A) True.

Additional information:
The relation between force and pressure is given as.
Pressure is the force per unit area. i.e.
$P = \dfrac{F}{A}$
$F = $ Force in $N$
$A = $ Area in ${m^2}$
$P = $ Pressure.

Note:You need to remember that any liquid is always pushed from the higher pressure to the lower pressure. You can use the same concept to observe how blood is taken out in a syringe by doctors. It happens because the pressure inside the vein is higher than the pressure inside the syringe.
