A student wishes to determine the volume of an irregularly shaped piece of cork. Their experiment requires the use of a heavy lead sinker of mass 226 g.
Calculate the volume of the lead sinker. The density of lead is 11.3 g/cm3.
To find the volume of the piece of cork, the student has a measuring cylinder, a supply of water, and the lead sinker from (a). The piece of cork and the lead sinker are both small enough to fit inside the measuring cylinder.
The piece of cork floats on water. Explain why.
Describe how the student can find the volume of the piece of cork, stating the measurements that need to be made and any calculations required.
