YGKScientific Scales

YGK Scientific Scales

QuestionAnswer
Temperature scale assigns a value of 0°C to the freezing point of water (at a pressure of 1 atmosphere), and 100°C to the boiling point of water (at the same pressure) Celsius
Scales are based on straight lines: equal differences between values on the scale indicate equal differences in the phenomenon being described. Linear Scales
Temperature scale based on the triple point of water, the point at which water’s solid, liquid, and gaseous phases can coexist in equilibrium Kelvin (do not say degrees Kelvin)
Numbers that measure speed. It is defined as the ratio of the speed of an object to the speed of sound in the same medium Mach number (Mach 1=speed of sound, 343 m/s)
This scale can describe any kind of power, but is most commonly used to describe the intensity of sound waves Decibel Scale
Used to quantify acidity. Ranges from 0 to 14. Any number greater than 7 is considered a base and any number less than 7 is considered an acid. pH Scale
This scale measures earthquake intensity; ranging from 0-10 Richter scale
This scale is primarily based on wind speed, but also incorporates descriptions of wave height, sea conditions, and land conditions. In most parts of the world, it stops at 12, which is designated “hurricane-force winds. Beaufort scale
These scales measure tornado strength. F0 to F5 (wind speeds of 260 mph) Fujita-Pearson and Enhanced Fujita scales
This scale is based on the abilities of minerals to scratch one another. The original scale assigned a value of 1 to talc, which can be scratched by essentially every solid known, & a value of 10 to diamond, which can only be scratched by other diamonds. Mohs Hardness Scale
One of several scales that measure electronegativity, the attraction of atoms for electrons in chemical bonds. Higher values correspond to stronger attractions. Pauling Scale
This scale is a measure of wind speed and damage from hurricanes. It rates hurricanes on a 1-to-5 scale: a 1 corresponds to a wind speed of 74-95 miles per hour. A 5 causes “catastrophic damage,” with wind speeds over 157 miles per hour Saffir-Simpson scale
