Flow of Energy A. Introduction 1. living organisms a. we all need energy to sustain life b. we cannot make energy c. we cannot recycle energy d. we can transform energy B. Energy transformation 1. Energy- ability to do work a. must have gradient or no work is done b. Radiant energy (electromagnetic) c. electrical energy- Radiant energy→electrical energy→chemical(glucose)→Mechanical, sound d. chemical energy e. mechanical energy f. sound energy g. heat energy 2. Thermodynamics- study of the transfer of energy (through measuring heat) a. Laws of Thermodynamics - First Law of Thermodynamics (1 st law of thermodynamics) i. the total energy in the Universe is constant ii. Energy cannot be created nor destroyed H = G +TS (H (enthalpy), G (free energy), S (entropy), T(temp.)) iii. enthalpy- total energy iv. free energy- useful energy, has gradient, use do to work v. entropy- useless energy, disorder energy, unorganized, random energy vi. temperature- temperature - Second law of thermodynamics
