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.
