Question

When you drink liquid through a straw, is it more accurate to say the liquid is pushed up the straw rather than sucked up the straw? What exactly does the pushing? Defend your answer.

Answer 1

the liquid is pushed up the straw

Step-by-step explanation:

Liquid is pushed up the straw . It is not sucked up . It is pushed up by force created by atmospheric pressure difference created. by sucking we create a pressure difference . This pressure difference creates force that pushes liquid in the mouth.

We can not drink liquid by sucking it through straw on moon , because moon has no atmosphere so pushing force is absent there.
