Question

multiple choice questions. the accompanying data table shows the mass and volume of four different minerals. use your answer(s) to the following question(s) on the earth science reference tables and on your knowledge of earth science. does increasing the temperature of a material change its density? explain why or why not. mineral sample mass volume a 50 g 20 ml b 60 g 15 ml c 55 g 10 ml d 40 g 5 ml

Explanation:

Step1: Recall density formula

Density ($
ho$) is given by $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Calculate density of sample A

For sample A, $m = 50g$ and $V=20mL$. So, $
ho_A=\frac{50g}{20mL}=2.5g/mL$.

Step3: Calculate density of sample B

For sample B, $m = 60g$ and $V = 15mL$. So, $
ho_B=\frac{60g}{15mL}=4g/mL$.

Step4: Calculate density of sample C

For sample C, $m = 55g$ and $V=10mL$. So, $
ho_C=\frac{55g}{10mL}=5.5g/mL$.

Step5: Calculate density of sample D

For sample D, $m = 40g$ and $V = 5mL$. So, $
ho_D=\frac{40g}{5mL}=8g/mL$.

Answer:

Sample D has the greatest density.
