Seite 201 - The ratio of the mass of a body to the mass of an equal volume of water at 4° C.
Seite 208 - The refractive index («) of a substance is the ratio of the velocity of light in a vacuum to its velocity in the substance . It varies with the wavelength of the light used in its measurement.
Seite 302 - What is the acceleration toward the center of a point on the equator due to the rotation of the earth?
Seite 197 - Avogadro's principle or hypothesis, which states that equal volumes of all gases under the same conditions of temperature and pressure contain the same number of molecules, was the extension of Dalton's Atomic Theory necessary to put the theoretical interpretation of chemistry on a solid foundation.
Seite 90 - The standard scale, which consists of 10 common minerals arranged in order of increasing hardness, is as follows: 1. Talc 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond By using the above reference minerals, the hardness of an unknown mineral can be determined.
