Question

Use the graph to answer both parts of this question about these three minerals. Do not use calculations.

Answer 1

Answer:

$\boxed {\boxed {\sf Mercury \ is \ the most \ dense \ and \ titanium \ is \ the \ least \ dense}}$

Explanation:

The formula for density is:

$d=\frac{m}{v}$

As mass and volume increase, so does the density.

In this problem, the density is the line. So, the steeper the slope of the line, the greater the density.

• Mercury (Hg) is the most dense because it has the steepest slope.
• Copper (Cu) is more dense than titanium but less dense than mercury.
• Titanium (Ti) is the least dense because it's slope is the least steep.

So, mercury is the most dense and titanium is the least dense.

Answer 2

Answer:

Mercury is the most dense whereas Titanium is the least dense.

Explanation:

Since Density = Mass / Volume, the slope of the line can immediately tell us its relative density between the metals.
