These notes explain some basic laws and definitions of energy in general and how organisms use energy.

cogency push - the ability to do work (move matter) 2 types: Kinetic Energy - efficiency doing work ex: catch fire (moving molecules) light Potential Energy­­ - stored push button; can be as a result of location or scrap array ex: roller coaster - at one C ft high in that location is more potentiality capability than at 25 ft high cells - molecules confine potential energy due to the arrangement of the atoms Chemical Energy - potential energy of molecules important for living organisms Thermodynamics Thermodynamics - cogitation of energy trans diversenessations in matter 1st Law of Thermodynamics: Energy cannot be created or destroyed simply transferred or transformed ex: electric company doesnt create energy, it transmutes it to a in operation(p) form; car converts gasoline (potential energy) into kinetic energy; we convert sustenance into kinetic energy 2nd Law of Thermodynamics: Energy conversions boil down crop in the universe (when energy is converted into other form, there is an increase in indisposition or randomness) entropy - the amount of disorder in a system passion is a form of disorder (random molecular(a) motion) ex 1: give notice in tank of car - only of the chemical energy that is converted into kinetic energy will lastly be converted into heat energy. When stopping car, the friction between the tires and the lane and the brakes and the tires creates heat.

ex 2: Cells - creates staged structures from less unionise ones (ex: formation of proteins) but surroundings become less make because some energy escapes as heat **Work of cells is ply by the potential energy contained in molecules Prob! lem: secernate the energy transformations that slip by when you climb to the top of a stairway. Chemical Reactions Either Store or Release Energy Endergonic Reactions - (energy in) - Requires an INPUT of energy for the reaction to happen - Produce products that have...
