The same is true in hypothesis - a possible science, except that the word theory is reserved for a single explanation supported by lots of evidence collected over a long period explanation that can be tested by of time. creates hot must go away or weaken as the coffee gets cold (Figure 2.3). CHAPTER 2 SCIENCE AND MEASUREMENTRelationships between distance, speed, and time Mixing up A common type of question in physics is: How far do you go if youdistance, speed, drive for two hours at a speed of 100 km/h? You know how to get speed from time and distance. The carbon atoms in diamond are volumes and densities. The volume of a rectangular solid (a shoebox shape), for example, is found by multiplying length times width times height. 7:50 a.m. The Book of Fire Cottrell Mountain Press 1. 7.4 g/mL; b.

Enrique wonders what happens to hot objects if you remove them from the stove. solder takes up 52.6 mL. Mass is Although mass and weight are related quantities, always remember the fundamental difference. For instance, a solid are often expressed as g/mL, g/cm3, block of wood and a solid block of steel can have the same volume, but they would not have or kg/m3 the same mass. Not only do scientists and engineers use math and technology to answer questions and solve problems in each field, but so do students practice science when they make choices and solve problems. A car has more mass than a bicycle because the car contains more matter. 2.2 Review 41 Does what other people think qualify as scientific evidence?
