GEOG 101 Lecture Notes - Lecture 4: Calorie, Daniel Gabriel Fahrenheit, Kelvin
Document Summary
Calorie-energy needed to raise the temperature of a gram of water 1 c. The sun emits energy at a rate of 105,000 calories/cm2/minute. Heat- energy that is transferred form an object with a higher temperature to an object with lower temperature . Increases internal energy in the cooler object. Decreases the internal energy in the warmer object. Freezing point at sea level = 32 f. Boiling point at sea level = 212 f. Freezing point at sea level = 0 c. Boiling point at sea level = 100 c. Scale begins at absolute zero = 0k. Covered louvered white structure 1. 5 meters above the ground with a calibrated mercury thermometer. Source-medium sized, medium temperature star (the sun) Stefan-boltzman law-the hotter an object is, the greater the flow of energy from it will be f=kt4, where f=radiation flux in langley"s/minute, t=temperature in degrees kelvin, and k=constant of 0. 813 x 10-10 calories/cm2/minute.
