Question

Imagine a 10 kg chunk of aluminum (density = 2.7 g/cm3) and a 10 g chunk of iron (density = 7.9 g/cm3).

Answer 1

The answer is C.
Hope this helps!!!

Answer 2

Answer:  C. The chunk of iron's volume is smaller than the chunk of aluminum's volume.

Step-by-step explanation:

Given: The mass of aluminum chunk = 10 kg

In grams , the mass of aluminum chunk = 1000 g   [∵ 1 kg = 1000 g]

The mass of iron chunk =10 g

i.e The chunk of aluminum is more massive than the chunk of iron.

Density of Aluminum chunk = $2.7\ g/cm^3$

Density of iron chunk = $7.9\ g/cm^3$

The formula of volume is given by :-

$\text{Volume}=\dfrac{\text{Mass}}{\text{Density}}$

$\text{Volume of Aluminium chunk}=\dfrac{1000}{2.7}=370.37\ cm^3$

$\text{Volume of Iron chunk}=\dfrac{10}{7.9}\approx 1.27\ cm^3$

Clearly, The chunk of iron's volume is smaller than the chunk of aluminum's volume.
