Question

A graduated cylinder is filled to an initial volume of 12.7 ml. A rock Is dropped into the graduated cylinder. The final volume of the graduated cylinder is 18.2ml. What is the Rocks volume in both ml and cm3? What method was used to determine this?

Answer 1

First of all, ml and cm^3 are equal. The volume of the rock is 5.5 ml. This is found by subtracting the volume of just the water from the combined volume of the rock and the water leaving you with just the volume of the rock. This is method is using water displacement.

Answer 2

Answer:

V = 5.5 mL

Explanation:

The volume filled in the graduated cylinder is 12.7 mL

now when a stone is dropped into the cylinder then the volume of liquid is raised to final level of 18.2 mL

so as per the theory of given by Archimidies we can say that the volume of the object is exactly same as the volume displaced by the object

So here the volume displaced by the object is given as

$V_{displaced} = V_f - V_i$

$V_{displaced} = 18.2 mL - 12.7 mL$

$V_{displaced} = 5.5 mL$

so the volume of the object is given as

$V = V_{displaced}$

$V = 5.5 mL$
