Density

Which material has the greatest density?

• A

• B

• C

• D

The density of cube A is

• 0.26 g/cm³

• 3.8 g/cm³

• 0.38 g/cm³

• 2.6 g/cm³

The mass of cube B is measured in order to calculate its density. The cube has water on it while its mass is being measured. How would the calculated value for density compare to its actual value?

• The calculated density value would be greater than the actual density

• The calculated density value would be the same as the actual density

• The calculated density value would be less than the actual density

The density of the material in cube A is determined at different temperatures and phases of matter. At which temperature and in which phase of matter would the density of cube A most likely be greatest?

• at 200^oC and in the solid phase

• at 1800^oC and in the liquid phase

• at 20^oC and in the solid phase

• at 2700^oC and in the gaseous phase

If cube B is removed from cube A, the density of the remaining part of cube A will

• increase

• decrease

• remain the same

If pressure is applied to cube A until its volume is one-half of its original volume, its new density will be

• one-half its original densit

• twice its original density

• the same as its original density

• one-third its original density
