Question
The density of water is 1000 kg/m3 and the density of copper is 8900 kg/m3. Which of the following statements is incorrect?
Options
`"The density of a certain volume of copper"/"The density of the same volume of water"` = 8.9
`"The volume of a certain mass of copper"/"The volume of the same mass of water"` = 8.9
`"The weight of a certain volume of copper"/"The weight of the same volume of water"` = 8.9
`"The mass of a certain volume of copper"/"The mass of the same volume of water"` = 8.9
Solution
Density = `"The volume of a certain mass of copper"/"The volume of the same mass of water"` = 8.9
This is because the density is defined as the ratio of the mass of the object to the volume of the object.
