Question

Which pressure is helpful to drink juice

Answer 1

Answer:

atmospheric pressure

Explanation:

When you close your mouth and seal your lips over the open - presumably upper - end of the straw, and manipulate your cheeks to increase the volume of the space enclosed within your mouth - and so too the airspace within the straw, as necessary to “suck” fluid from the straw, the increase in the effective volume of this sealed cavity produces a corresponding reduction in the prevailing absolute pressure.
