| 65 | par. 1, lines 5–7 | "Unlike many colloids, liquid solutions appear clear and transparent. The particles in a liquid solution are too small to scatter light." | "Unlike many colloids, the particles in a liquid solution are too small to scatter light." |
| 66 | Fig. 3-12: Types of Solutions | Figure lists five different types of solutions. | Figure should list seven different types of solutions. The correct figure should include two additional rows after the "Gas/Gas" entry. The new copy is "Gas/Liquid/Soda water (carbon dioxide in water)" and "Gas/Solid/Charcoal gas mask (poisonous gases on carbon)." |
| 66 | Fig. 3-12 caption | "Solutions can be observed in each of the three different physical states. Which type of solutions do you think are most common?" | "Seven different types of solutions can be made from three different phases of matter. Can most solutions be separated by simple physical means? Explain." |
| 73 | par. 1, line 1 | "Most compounds are made of molecules...." | "Compounds are made of molecules...." |
| 79 | Summarizing Key Concepts, Sec. 3-4, Item 2 | "Most compounds are made of molecules...." | "Compounds are made of molecules...." |
| 168 | Glossary | "actinoid series: second row of rare-earth elements in the periodic table; radioactive; all but three are synthetic" | "actinoid series: second row of rare-earth elements in the periodic table; radioactive; all but four are synthetic" |
| 169 | Glossary | Insert new text: "nuclear fission (FIHSH-uhn): splitting of an atomic nucleus into smaller nuclei of approximately equal mass" "nuclear fusion: joining of two atomic nuclei of smaller mass to form a single nucleus of larger mass" |
Corrections of typographical or grammatical errors.

| 18 | Fig. 1-7, caption, lines 3–5 | "...a mountaintop than on the surface of the Earth. Why would a person weigh more on the Earth's surface than on a mountaintop?" | "...a mountaintop than at sea level. Why would a person weigh more at sea level than on a mountaintop?" |
| 25 | par. 2 | "The density of water increases with depth. In other words, the density of water increases as you go deeper under the surface of the water. So the density of deep water is greater than 1 g/mL. At a certain depth, the scuba diver's density is equal to the water's density. The diver will not be able to sink below this depth." | "To return to the water's surface, the diver's overall density must be less than 1 g/mL. How can the diver decrease her density? By increasing her overall volume without significantly increasing her mass. Divers wear a vest that they can fill with air. As air enters the vest, the diver's volume is increased, but the change in mass is very small. This increase in volume decreases the diver's density to less than 1 g/mL, causing the diver to slowly rise to the water's surface." |
| 25 | par. 3 | "While the Mary Rose moved on the surface of the ocean, her hull was partly filled with air. The air helped to make the ship's overall density less than 1 g/mL, so it floated. Keep in mind that the overall density is equal to the total densities of the ship, the air within the hull, the cannons and cargo, and the people aboard the ship. Because the density of air is so low, the large volume of air balanced the mass of the ship and its cargo. However, when water, which is more dense than air, replaced some of the air in the hull, the overall density increased too much." | "While the Mary Rose moved on the surface of the ocean, her hull was partly filled with air. The air helped make the ship's overall density less than 1 g/mL, and so it floated. The large volume of air balanced the added mass of the heavy bronze cannons. However, when her hull partially filled with water, the overall density of the Mary Rose, her heavy cannons, and the water became greater than the density of the surrounding water at any depth." |

| 46 | Problem Solving graph | The slopes of the phase-change diagram's "solid", "liquid", and "gas" parts. | The slope of the phase-change diagram's "liquid" part should be twice as steep as the "solid" and "gas" parts. |
| 47 | Fig. 2-18, caption, lines 3–6 | "Dry ice becomes carbon dioxide (top) and iodine crystals become gaseous iodine (bottom)." | "Dry ice (top) becomes gaseous carbon dioxide and iodine crystals (bottom) become gaseous iodine." |
| 85 | Fig. 4-2, caption, lines 7–9 | "...of a dead companion, was made about the time Democritus lived." | "...of a dead companion, was made close to the time Democritus lived." |
| 103 | Summarizing Key Concepts, Section 4-2, item 7 | "The atomic mass of an element is the average mass of all the naturally occurring isotopes of that element." | "The atomic mass of an element is the average mass of all the existing isotopes of that element." |
