Document Summary
Temperature and wavelength: review of last time a. b. c. d. You can"t trust the data (or the experts) The climate was warming, but it has stopped . The climate has always changed : energy, climate is defined by temperature, which is defined by energy, many kinds of energy b. i. b. ii. Climate begins with the sun: energy in = energy out, to understand climate, you need tools d. i. d. ii. In this class, focusing on internal energy (the earth): f. f. i. How fast the atoms are moving: measure energy using joules (j) g. i. 1j = 0. 239 calorie (cal) [not a food calorie, that"s 1000 cal: temperature is related to energy h. i. h. ii. h. iii. h. iv. Add energy to water and increase its internal energy. If you know the temperature, you know the internal energy of an object h. iv. 1. Higher = very hot, low = cold: new temperature scale: kelvin. 10km up in the atmo = -73* c.
