The rock is less dense than the liquid.
The rock is more dense than the liquid.
The rock and the liquid have the same density.

It is not too late to review! Mass Volume Density
2) A sample of a mineral is heated until it melts. Compared to the density of the original sample, the density of the melted sample most likely will be

less
greater
the same

3) What is the density of a mineral sample with a volume of 10.00 cm^{3} and a mass of 25.0g?

2.5 g/cm^{3}
25.0 g/cm^{3}
250.0 g/cm^{3}
.25 g/cm^{3}

Base your answers to questions 4 , 5 , and 6 on this object.

Mass = 80.0 grams

Volume = 25 g

4) What is the density of the object

1.3 g/cm^{3}
5.5 g/cm^{3}
3.2 g/cm^{3}
0.3 g/cm^{3}

5) The mass of the object could best be determined by

comparing it with a known standard mass.
placing it in a beaker of water.
calculating its circunference.
counting the number of flat surfaces it contains.

6) If the object is cut in half, the density of each piece will be

less than that of the original object
greater than that of the original object
the same as that of the original object

Base your answers to questions 7 , 8 , and 9 on this object.
7) The mass of this piece of material is approximately

.23 g
4.4 g
9.3 g
32.4 g

8) Which graph best represents the relationship between the mass and volume of various sized pieces of this material?

9) If this material is heated and expands, the density of the material will

decrease
increase
remain the same

10) As Shown below, an empty 1,000 milliliter cylinder has a mass of 250.0 grams. When filled with a liquid, the container and the liquid have a combined mass of 1,300 grams.

What is the density of the liquid?

1) 1.00 g/cm^{3}

2) 1.05 g/cm^{3}

3) 1.30 g/cm^{3}

4) 0.95 g/cm^{3}
