GEOG 2050 Chapter : Chapter 5 Notes
Document Summary
Key concepts: temperature, heat, absolute zero, celsius, fahrenheit, kelvin, mercury thermometer, alcohol thermometer, thermistor, daily mean temperature, daily temperauture range, monthly mean temperature, mean monthly temperature, annual mean temperature, annual temperature range, seas surface temperature (sst) Temperature: heat = energy of molecular movement along gradient, temperature = average kinetic energy (motion) of molecules, heat measured in calories, raise temperature of 1g water by 1o c, 1000 food calories = 1 calorie. Temperature scales: fahrenheit (degrees fahrenheit, celsius (degrees c, kelvin (k) Celsius (degrees c: also known as centigrade scale, water (h2o) at atm, o degrees c = freeze/melt point, 100 degrees c = boil/steam point, 100 degrees c separate freezing from boiling points, used worldwide. Ratio of 100:180 or 1 degree c = 1. 8 degrees f. Measuring temperature: for official readings, outdoors, white shelters, high albedo, louvered for ventilation, 1. 2 meters above a grass surface, shade, daily or hourly.
