why is it necessary to measure it's volume using a measuring cylinder or eureka can?
Answers
Answer:
To illustrate the effects of precision on data, volumes will be determined by three different methods: geometrically (measuring lengths); water displacement; and pycnometry. The composition of a mixed brass-aluminum cylinder and the volume of empty space within a hollow cylinder will also be found.
Explanation:
These cans can be purchased through most lab suppliers. Measuring cylinders can be used instead of these cans to achieve the same effect.
The can is filled as high as possible with water and an object inserted slowly into it. As the object fits into the can, the water it displaces pours out of the spout. This displaced water can then be measured and will be the same as the volume of the object. For example a 10 cm³ cube will displace 10cm³ of water.
The density of some common objects are listed below for comparison:
