Is it true that liquids rise in a straw because of suction?
yes <><><><><> Actually, the pressure outside the straw presses the fluid up into the straw.
Why a liquid travels up a straw when you suck on it?
1) Air inside the straw moves 2)Pressure inside decreases 3)Pressure of the atmosphere is greater then the Pressure inside the straw=Liquid moves up the straw!!!
Why does a soft drink rises when sucked with a straw?
As you suck on the straw air is removed from the inside of the straw and the air pressure within the straw is reduced. Once the straw's air pressure is reduced past atmospheric pressure of about 760 mmHg, the Patm forces the drink up the straw and into the sucker's mouth. Gases move from high to low pressure areas until equilibrium is reached.

When measuring a small quantity of liquid which instrument would permit the most accurate reading?
If available, a small, glass graduated cylinder would be best. Next best would be a test tube or any clear or semi-transparent cylinder/ small plastic recycled container/bottle. If an eyedropper is not available, recycle a milkshake straw to move/transfer small quantities of a liquid. Place the bottom end of the straw in the liquid almost to the bottom. Then hold your thumb tightly to the top end of the straw and lift out of the liquid. When you remove your thumb the contents will spill out of the bottom of the straw.

Not quite. While they are similar shapes, a cylinder is usually solid (like a peg or a tin can, before it is opened) while a tube is hollow (like a pipe or a straw).
What is the formula for calculating the capacity of a drinking straw?
A standard drinking straw is a cylinder. The formula for calculating the volume of a cylinder is: Pi x r2 x length. So, a drinking straw that is 9.5 inches long with a diameter of .25 inches (1/4 inch) has a volume calculated like this:Pi (3.1416) x radius squared (.1252 = 0.015625) x length (9.5) = 0.46633125 cubic inches
