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 = [tex]2.7\ g/cm^3[/tex]
Density of iron chunk = [tex]7.9\ g/cm^3[/tex]
The formula of volume is given by :-
[tex]\text{Volume}=\dfrac{\text{Mass}}{\text{Density}}[/tex]
[tex]\text{Volume of Aluminium chunk}=\dfrac{1000}{2.7}=370.37\ cm^3[/tex]
[tex]\text{Volume of Iron chunk}=\dfrac{10}{7.9}\approx 1.27\ cm^3[/tex]
Clearly, The chunk of iron's volume is smaller than the chunk of aluminum's volume.
