Document Summary
Define the 1st and 2nd laws of thermodynamics. Explain why the 2nd law forces animals to eat food. Stored energy (energy that is present in universe but not currently doing any work) Example: when a glass is sitting on top of a table. Energy of moving objects (particles, atoms, etc. ) Example: when glass falls off the table (it creates kinetic energy) Most important for life on earth (the source of all life on earth) Waves in electromagnetic field that permeates our universe. Light is an aspect of radiant energy. Energy that exists between covalent bonds in molecules in food, the body, etc. Can be used by animals to work ** Can be potential if you look at the differences between two points. Example: a series of atoms moving in the same direction. The ultimate amount ofrandom kinetic energy existing in a system. Temp. is a measure of how much heat there is on average.
