A student measures the mass and volume of two irregular-shaped objects, one iron and the other copper, using the apparatus shown in Fig. 1.1.
Table 1.1 gives the outcomes obtained.
(a)[2]
Describe how to determine the volume of an irregular object with a measuring cylinder.
(b)[2]
Calculate the density of iron.
(c)[2]
A third copper object has the same volume as the iron object. Calculate the mass of this copper object.
(d)[1]
State and explain the change in the density of the iron object as it is heated.
