EXERCISE 3 (GPH 214) OBJECTIVES : The objective of this exercise is to familiarize you with two important elements of weather: temperature and humidity. Upon completing this exercise you should be able: 1. to calculate temperature conversions in the Fahrenheit, Celsius, and Kelvin scales. 2. to calculate temperature lapse rates. 3. to describe and explain the signicance of a "continental " climate. 4. to use global isothermal maps to examine global temperature variations and to explain the factors contributing to these variations. 5. to explain the difference between absolute humidity and relative humidity and to explain the relationship between temperature and atmospheric humidity. 6. to calculate relative humidity and to compare relative humidity data for different locations and times. Temperature (Part I) Three temperature scales are in common use: Fahrenheit (F), Celsius or centigrade (C), and Kelvin or absolute (K). The scientic world has adopted the Celsius scale for most uses although Kelvin is sometimes most appropriate in some equations and laws. In this lab, the Celsius scale generally will be used. 1) a. Give the values of the following in the three temperature scales (use textbook, Internet, etc.): \"F 0C \"K Freezing point of water Boiling point of water
