Question

Equal volumes of iron and aluminum have different masses because they have different _________ .

• A. shapes
• B. densities
• C. lengths
• D. times

Answer 1

Answer: (B)

densities

If volume of iron = Volume of aluminium

then mass of iron > mass of aluminium

${\rho }_{iron}\times V_{iron}>{\rho }_{aluminium}\times V_{aluminium}$

${\rho }_{iron}>{\rho }_{aluminium}$
