Chapter 2 Science Skills VOCABULARY 2.2 Determining Density density the mass per unit volume of a given material; units for density Mass and volume are different properties of matter, but they are related. 5. You arrive at describe the same speed? However, you will encounter a much wider range of masses in science. How did the wasps do it? believed. CHAPTER 2 SCIENCE AND MEASUREMENT2.1 Inquiry and the Scientific MethodScientists believe everything in the universe works by a set of rules called natural laws. Strictly speaking, a line graph does not usually show cause and effect. The way people came to understand the solar system is a good example of how new evidence leads to new and better theories (Figure 2.5).32 UNIT 1 THE PHYSICAL SCIENCES c. I went to the Moon and I lost mass, even though I didnt lose any of my matter. How many millimeters is represented by 6.7 cm? Foam is light and airy, or low density, and even a large volume of foam has very little mass. If something moves at a constant speed, what do you know about the distance it moves each second? For is independent of example, a steel nail and a steel cube have different amounts of matter and shape therefore different masses (Figure2.10). correct theory. 4. This gives us confidence that the current theory is the right one; 2. or the current theory does not explain the new evidence. Ancient peopleTesting the The caloric theory explained what people knew at the time. Brick is heavy, or high density, and therefore contains a lot more mass per cubic centimeter than foam.

The fundamental center of the meniscus, which is the unit of volume in SI is the cubic meter (m3). The speed illustration below shows the position of each bicycle at one-second intervals. are alive because of an undetectable life force. This is not a scientific hypothesis because there is no way to test it. a. You will at least make progress toward an answer every time. 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. person on Earth?

SSC has released a total number of 4300 vacancies for the SSC CPO Recruitment 2022. Record the name of the object in the first row of the table. Instead, set things gently on the balance. Science Skills 2CHAPTERFOR SAMPLE ONLY - NOT FOR CLASSROOM USE No one knows the importance of including the correct unit with a measurement like NASA (National Aeronautics and Space Administration). Mass is the amount of matter in an object. You can also damage the balance if you press down on the cover plate with your hand. This can be tempting, but dont doit! 2.2 Determining Density 39 Masses you will Ordinary objects tend to have masses between a few grams and a few consider in science hundred kilograms. The density of the aluminum can is called its average molecules relatively tightly packed. ISBN 9780030672132. Look for words like constant or at rest.

Holt Science Spectrum: Physical Science with Earth and Space Science : Student Edition 2008. Eventually, the detective comes up with a theory about what happened. The volume of a rectangular solid (a shoebox shape), for example, is found by multiplying length times width times height. 120 0.0009 0.9 Figure2.9: Density of some commonmaterials. However, physical science is about the true nature of how the universe works, so it is time for us to learn and understand the difference between mass and weightand there is a big difference!

The average density Suppose you have a piece of aluminum foil, a length of aluminum wire, and of a hollow object an aluminum brick. (Hint: Dont forget to check the illustrations.) After many experiments, Mayers hypothesis that heat was a form of energy became the accepted theory of heat we believe today (Figure 2.4). they are the same distance (59 miles) That tells us we divide 95 by 1.609 to get 59 miles. The relationships between force and motion are known as Newtons laws. relatively huge volume for laboratory work, about the size of the inside of a Figure2.5: The key displaced 3.0 mL refrigerator.
