An archaeologist wants to determine the density of an irregularly shaped metallic relic discovered at an excavation site.
Describe how the archaeologist could experimentally measure the volume of this irregular metallic relic.
The volume of the relic was measured as 14.0 cm314.0\text{ cm}^314.0 cm3.
The archaeologist measured the mass of the relic as 123.9 g123.9\text{ g}123.9 g.
Calculate the density of the relic in g/cm3\text{g/cm}^3g/cm3.
Use the equation: density=massvolume\text{density} = \frac{\text{mass}}{\text{volume}}density=volumemass
Figure 1 shows the densities of different types of ancient alloys and metals.
Based on your calculated density, what is the most likely material of the relic? Select one option:
- Cast Iron
- Tin
- Brass
- Bronze
- Silver
Give one source of error that may have occurred when the archaeologist measured the volume of the relic.
How would the error you described in Part 4 affect the measured volume of the relic?
Changes of state and the particle model Questions
Practise AQA GCSE Physics Changes of state and the particle model with exam-style questions for Foundation and Higher tier. 25 questions covering Density of materials and Changes of state, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
