### Graduated Cylinder is used to measure what?

A graduated cylinder measures liquid volume. The word
"graduated" means it's marked off in units, usually milliliters
(mL). Because the cylinder is graduated more finely than most
beakers or flasks, the graduated cylinder is the best way to
accurately measure liquid volume in science. Beakers and flasks can
give you a rough measurement, but graduated cylinders are the way
to go if you really want to be accurate.

### What tool would you use to find the volume of an expo marker?

The best way to find a volume of anything(that doesn't dissolve
or get damage by water) is by simply filling a graduated cylinder
with water(amount doesnt matter)then dipping the object in water
and calculating the difference. (FOR EXAMPLE: I can fill a
graduated cylinder up to 100 ml. Then i will dip the expo marker in
it. And let's say for example that it rises by 50 ml. Then the
volume is 50 milliliters.)

###### Asked in Measuring Tools

### What would you use to measure volume?

It depends on the amount you want to take. If it is microlitres,
you can use a micropipette, millilitres, a pipette (a burette would
be more accurate), and if greater than that, it is best to use a
large graduated cylinder. A graduated cylinder is more inaccurate
than a pipette, but at volumes of 500ml for example, it is
impractical to use a pipette.

###### Asked in Rice

### How do you work out the volume of a grain of rice?

the best and most accurate way would be to find a container that
measures volume accurately (a graduated cylinder would work well)
and fill it with a known amount of water(say, 10 mL). Then count
out a number of rice grains (20 or 30 would be enough) and drop
them into the the cylinder with the water. Tap the cylinder to make
sure there are no bubbles attached to the rice grains, and then
record the total volume or the rice and the water (or where the
water is up to on the cylinder). If you subtract the volume of the
water (the first measurement) from the volume of the rice+water
(the second measurment) you will get the volume of the rice. Divide
by the number of grains, and you'll have the average volume of a
grain of rice.
if you want to find the volume of a particular grain of
rice, then you can do the same process with just one grain of rice,
but you will need something that measures volume much more
accurately than a graduated cylinder

###### Asked in Chocolate Chips

### How can you find the volume of a chocolate chip?

The best way would be to drop a few chocolate chips into a
graduated cylinder filled halfway with water. Be sure to note the
volume before and after adding the chips. The volume will be equal
to the difference in volume divided by the number of chips
added.
Note: do not melt the chocolate chips because the volume will
change with temperature and type of fat crystal structure.

###### Asked in Chemistry

### Which is more precise a 125 mL Erlenmeyer flask or a 50 mL graduated cylinder concerning significant figures?

As far as sig figs are concerned, the graduated cylinder will
yield a measurement that is both more precise and accurate than is
possible using an Erlenmeyer (precision and accuracy mean different
things in science talk). Erlenmeyer flasks aren't really intended
to be used for measurement of volume, as the width of the flask at
the point of the markings introduces lots of error as you try and
eyeball the level of fluid within it. The narrow column of a
graduated cylinder will allow you to judge volume far more
accurately since a difference in the height of fluid in one of
these will result in a lower overall difference in volume when
compared to the Erlenmeyer.
Keep in mind though, that just because a graduated cylinder
contains a certain volume doesn't mean that it will
deliver that entire volume to another container, since some
of the liquid inevitably clings to the sides. This isn't a problem
is you are simply trying to measure volume, but if you are trying
to pour an exact volume into another container you need to use
another method to do so. In this case your best bet is to
pipette.

### What is the radius of a cylinder with a volume of 980?

To be able to find the radius of the cylinder, you need to know
not only its volume but also its height. The best we can do is find
an expression for the radius in terms of the height of the
cylinder
volume of cylinder = Pi x r2 x h
where r is the radius of the cylinder and h is the height of the
cylinder
980 = Pi x r2 x h
r = square root(980/(Pi x h))
