A student investigated the density of different decorative stones.
To find the volume of a stone, she used a displacement can filled with water up to the spout, submerged the stone, and collected the overflow in a measuring cylinder.
The student measured the volume of one stone three times. The three measurements were:
15.2 cm3,15.2 cm3,15.8 cm3 15.2\text{ cm}^3, \quad 15.2\text{ cm}^3, \quad 15.8\text{ cm}^3 15.2 cm3,15.2 cm3,15.8 cm3Calculate the mean volume of this stone.
A second stone has a mass of 42.0 g and a volume of 15.0 cm3.
Calculate the density of this second stone in g/cm3\text{g/cm}^3g/cm3.
Use the equation:
density=massvolume \text{density} = \frac{\text{mass}}{\text{volume}} density=volumemassPractise 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.
