Name # Date Period Still Dense About Density? Comprehension Skills Interpretative; Applied The density of a substance is its mass divided by its volume. This exercise will help you be less dense about density. The table at the right lists some substances and their densities. Look at the table carefully. Arrange the substances in the columns below in the order of their densities. Begin with the least dense substances and end with the most dense. Liquids Gases Solids Density of Some Common Substances Liquids Density g/cm 3 Carbon tetrachloride 1.595 Formalin 0.815 Methanol 0.796 Sulfuric acid 1.63 Water 1.0 Gases Air 0.0013 Carbon dioxide 0.0018 Helium 0.00018 Hydrogen 0.00005 Nitrogen 0.0012 Solids Ash wood 0.65 Balsa wood 0.37 Glass 2.6 Oak wood 0.68 Tin 7.18 If the statement is correct, write true in the space provided. If the statement is not correct, change the underlined word to make it correct. Write your answer in the space. 1. A block of ash wood will float in methanol. 2. Carbon tetrachloride will sink in sulfuric acid. 3. To float in air, a blimp could be filled with helium. 4. The same blimp might also be filled with carbon dioxide.
