Question

Out of three substances given below, which has the maximum density?

• A. Water
• B. Aluminium
• C. Copper

Answer 1

The correct option is C

Copper

1. Density is defined as the mass per unit volume. SI unit of density is $kg{m}^{-3}$.
2. We know, $Density=\frac{mass}{volume}$.
3. Relative density of water is 1, aluminium is 2.7 and copper is 8.9.

Hence, copper has maximum density and option (c) is correct.
