Question

Air pressure makes it possible for us to sip cold drink with the help of straw.

Answer 1

When we drink liquid with a straw ,the air pressure (due to our sucking)inside the straw decreases. The air pressure acting on the surface of liquid then becomes greater than the pressure inside the straw.

Answer 2

THIS MAKES LESS AIR PRESSURE INSIDE THE STRAW AND THE HIGHER PRESSURE OUTSIDE PUSHES THE WATER INSIDE THE STRAW
