Unformatted text preview: ty = mass volume or in terms of symbols: d= m V Density has units that are derived from the base units for mass and volume which are kilograms per cubic meter. However, it is more convenient to report densities in units of grams per cubic centimeter or grams per milliliter. Temperature Scales. Chemists use two temperature scales, the Kelvin scale (K) and the Celsius scale (°C). A third scale, the Fahrenheit scale (°F), is commonly used in the United States. The Celsius scale defines 0°C as the freezing point of water and 100°C as the boiling point of water. In the Fahrenheit scale the freezing point of water is 32°F and the boiling point is 212°F. The equation for converting from degrees Fahrenheit to degrees Celsius is: °C = (°F – 32°F) × 5°C 9°F To convert from degrees Celsius to degrees Fahrenheit, solve the equation for °F. See Example 1.6. The Kelvin scale will be discussed in Chapter 5.
