Question

Which two of the following are the densest of the materials shown?

Answer 1

Explanation:

The density of the material is given by,

Density = $\frac{mass}{Volume}$

Case 1: Rock

Density = $\frac{mass}{Volume}$

Density = $\frac{1000}{0.5}$

Density = 2000 $\frac{g}{L}$

Case 2: Pillow

Density = $\frac{mass}{Volume}$

Density = $\frac{200}{10}$

Density = 20 $\frac{g}{L}$

Case 3: Bottle of Soda

Density = $\frac{mass}{Volume}$

Density = $\frac{2000}{2}$

Density = 1000 $\frac{g}{L}$

Case 4: Load of bread

Density = $\frac{mass}{Volume}$

Density = $\frac{100}{1}$

Density = 100 $\frac{g}{L}$

Thus, rock and bottle of soda has maximum density.
