The question of what causes hot and cold puzzled people Figure 2.3: A question that might for a long time. Answers to these questionsinvolve experiments and variables. There are three ways to arrange the variables to find either distance, time, or speed. The density of a liquid is lower because the atoms are not packed as tightly as in a solid. Early hypotheses are rarely correct and are often modified as new evidence becomes available. Write 3,800 seconds in hours, minutes, and seconds. Read the mark at eye level.

Pine (wood) 600 0.44 To go from kg/m3 to g/cm3, you divide by 1,000. We and 59 mph are really the same because factors flip the conversion factor upside down so the units of km cancel out! Paraffin wax is also made mostly of carbon atoms, density because it also includes the air but the density is only 0.87 g/cm3 (870 kg/m3). 2. 4. 2.1 Review 35 List whether the gram (g) or the kilogram (kg) would be is a ____. Answer: 12 hours Figure 2.9: Using a formula.36 UNIT 1 THE PHYSICAL SCIENCES I'd been looking and looking for some kind of physical science textbook.

Do I have enough sugar to matter anything that has mass make a batch of brownies? A method of using conversion factors and unit canceling to solve accuracy mass significant a unit conversion problem is called . There are other types of graphs, but berelated scatterplots are the most useful for organizing and presenting physical science data.FOR SAMPLE ONLY - NOT FOR CLASSROOM USE Types of graphs Scatterplots, bar Most graphs are either scatterplots, bar, pie, or line graphs.
