Which two of the following are the densest of the materials shown?Material Mass (g) Volume (L)
Rock 1000 0.5
Pillow 200 10
Bottle of soda 2000 2
Loaf of bread 100 1

Answers

Answer:

The densest materials are rock and bottle of soda.

Explanation:

The density of material is given by,

Density = $(mass)/(volume)$

Case 1: Rock

Density = $(1000)/(0.5)$

Density = 2000 $(g)/(L)$

Case 2: Pillow

Density = $(200)/(10)$

Density = 20 $(g)/(L)$

Case 3: Bottle of soda

Density = $(2000)/(2)$

Density = 1000 $(g)/(L)$

Case 4: Load of bread

Density = $(100)/(1)$

Density = 100 $(g)/(L)$

The densest materials are rock and bottle of soda.
