Question

1) Density of iron is 7.8 g/cm³ and the density of copper is 8.9 g/cm³. For the same mass of iron

and copper:

Statement i) Volume of copper is more than Iron.

Statement ii) Volume of iron is more than copper.​

Answer 1

Answer:

statement II) is correct

Explanation:

density = mass ÷ volume

=> volume = mass ÷ density

when mass is same

volume is inversely proportional to density

therefore ,the higher the density , lesser is volume

as density of copper > density of iron

=> volume of copper < volume of iron

hence statement ii is correct

Answer 2

Explanation:

statement b is correct

bcoz density=mass/volume

and if volume is more ..... density would be less..so in case of iron this condition is satisfying
