Measuring Volume of a Bottle - Investigation
Take a "volume" measuring device, and fill it with the total amount of water, the bottle can hold.
We then put the same, empty bottle into the container, in a way, that it sinks to the bottom of the akwarium. We can then measure the new height and multiply it by the volume of the liquid.
This will clearly give us the volume of a bottle.
We could pour water into a 0,5 litre coke bottle, and weigh how much it would weigh.
We could do the same thing with an empty bottle. The difference of the two would give
us the weight of the water. This way we could easily calculate the voulume of the bottle,
as we all know, that the volume of the liquid given on the label could be pretty much
the same as the volume of the bottle. If the bottle is plastic, then there is not that
much of a difference. On the other hand, a glas bottle is much thicker, and would
have a slightly different volume.
If 1centimeter3 = 1 gram,
then (in this case) 500 centimeters3 would give us 500 grams.
From this we can see that the water weighs around 500 grams, and so this way, the volume
of the bottle would be around 500centimeters3 with a few decimal places (if we want to be accurate)
This is the last method, and the only sensible one that I could possibly think of. It is a method that could be taken under consideration, but I strongly feel, that it would be not as accurate as the earlier ones.
If the radius of the bottle = 2,5 cm.
And the height of the bottle = 15,3 cm,
Pi r2 h = volume of cylinder
